Contradiction? Whose rights are they protecting?

You call it what you want. I am inclined to agree with those who feel it was a
cheap hit. Do you seriously believe that if Apple had put out a possibly
infringing game, that SH would have chosen to go after them first? When you
want to set a precedent, it pays to try to set it against someone you are
pretty sure won't come back with a battery of lawyers to stomp you into the
dirt.

Why? If, as you stated at one point, SH is protecting their own rights, then
the author is not really involved. If, on the other hand, they are protecting
the author's rights, it's up to them to decide whether to keep the author
informed. Nastygrams to the author would be in order if the author was doing
the nasties.

I was not on one side or the other in this, right up until I saw the letter
from SH to Fred. In it, they stated that there were various key points which
they felt were grounds for pursuing the PD versions. One, in particular struck
me as odd, that being the number of different pieces. Since at least one of the
versions attacked has more pieces, and since at least one has pieces that act
differently, I feel that SH has overreacted by at least one step, knowing full
well that it would not be contested _at all_ by Fred. That leaves me with a lot
more respect for Fred than I have for SH.

EVERHART@arisia.dnet.ge.com (06/12/90)

It appears fairly clear we have witnessed in the recent withdrawal
of Tetris variants by Fred Fish a case of (to this point) successful
legal bullying.
   Let's get some issues clear. The idea for the tetris game can be
written down in a few lines, and ideas are not copyrightable. (This one
may also not pass muster as a useful invention for patent purposes, but
that's beside the point.) Here's a stab at this writing:
  Tetrominoes fall into a rectangular container (less top) under
control of the player. Whenever the blocks making up the tetrominoes
form a complete row across the width of the container, the row is
removed. Object of the game: keep the container from filling as long as
possible.
   The various games that have come out, some on the Fish disks, follow
this idea. They are however not duplicating Spectrum Holobyte's code
but are original works belonging to their authors and released to the
rest of us. SH is attempting to deprive these authors and their beneficiaries
(the rest of us) the benefits of their code.
   The analogy with Rubik's Cube is instructive. Repainting one certainly 
does not make a new or non-infringing cube. Replacing the guts with something
different, however, does. (This is also very nontrivial to do.) 
   Since SH cannot claim copyright infringement over the code, they are left
with the screen image. Their images have elaborate drawings as background,
which certainly make the totality copyrightable. However, the game board
part will if challenged in a technically competent forum certainly be seen
as too trivial to copyright. The relevant analogy is bitmaps of fonts. There 
are after all only five tetrominoes, and these shapes have been around for
generations. SH has explicitly disclaimed that they regard color as 
significant, so one is left with a board determined solely by the game idea,
which cannot be copyrighted. Their situation is much the same as if someone
copyrighted a drawing of a scene which included a 5x7 bitmap of an "M" and
then attempted to sue someone who used the same 5x7 bitmap of the "M".
   One hopes that SH got some code from ELORG, since if all they got was
the game idea, they paid for something that cannot be protected, save by
extra-legal bullying. Taking on Fred Fish, whose lack of deep pockets is
fairly well known, and who doesn't want to be involved in such controversies,
was a cheap hit. It does not show the SH case holds any water at all.
   I'm puzzled nobody seems to have asked whether the SH code plays
differently from the others. For example, is there some analysis built
into the SH engine which permits one to continue indefinitely with the
game which may be missing in the others? Or does this fall out of the
geometry of tiling an area with tetrominoes? (If the latter, a random
selection is adequate and one argues over the quality of random number
generators.)
   As for what to do, it seems clear that several steps are in order.
1. Sources other than the Fish disks should not regard Fred's withdrawal
	as having anything to say about SH's claims. The programs should
	be kept in circulation, denying SH any advantage in using threats
	to accomplish what it may not accomplish by valid legal protection.
	They risk encountering someone with deep enough pockets to defend
	their (and our) rights should they continue their tactics, and
	cannot hope to succeed in their object in any case.
2. This should be considered as a relevant item when thinking of buying 
	anything from SH in the future, and the issue should be made known
	to friends using other computer types. (There are many other Tetris
	clones out there on other platforms.)
3. Nastygrams to SH on the issue would not be inappropriate either.

	Finally, one of the variants uses the name Tetris. If the word
Tetris is a coined one, that variant should be renamed. However, someone
who knows Greek might ask if "tetris" is the Greek word for "four". If
that is the case, the trademark may be invalid (like the one that's been
applied for on "HyperText"...see Dr. Dobb's Journal, latest edition).
I would urge that it be renamed in any case (not that many Americans
speak Greek). This represents the usual action for trademark infringements.

Incidentally: the five tetrominoes (which those of you who read the
mathematical games section of Scientific American already should have
seen) are:
   XXXX    XXX  XXX  XX   XX
             X   X    XX  XX

Hmmm..  Either I'm misremembering it, or you have managed to get this
exactly backwards [and in fact this is a case *against* the point you
were trying to make]:  As I recall, some fellow in the US had developed
a Rubik's-like cube game using some kind of magnetic kludge to hold the
thing together.  The court found that Rubik's cube, despite having a
TOTALLY different mechanism [and despite that the original mechanism
looked very much like it would NEVER really work], infringed on the
fellow's patent.

	Let's make this clear.  SH is working on behalf of the original
author.  It's more accurate to say that the original author is working to
deprive these clone authors of the benefits of the derived games.

	Sorry, but SH >>MUST<< take on any and all distributors of
potential violators of their rights.  Or else they lose them.  It was
hardly a cheap hit; it was a necessary step on behalf of the Russian author.
If SH lets these go, then a commercial publisher can quite legally publish
a game called Tetrix and profit from it, since SH made no effort to
discourage distribution of similar games.

	Now, this line of reasoning is strongest against the
straight ahead clones and Tetris-namealikes.  Clearly, SH has the right
to stop distribution of a play-alike shareware game calling itself
Tetrix; it's not too hard to argue that it has the right to stop distribution
of PD software calling itself Tetrix.

	They are not on such strong ethical ground on playalikes that
do not call themselves by a similar sounding name.  BUt, here, too, they
are on stronger, legal ground; the vigor of their defense also protects them
against rivals who would usurp the name.  It's not a tactic I happen to
be happy with, but it's one they have the right to pursue.

	With Tetrix and other derivative names, they can hope and will
probably succeed.

a trademark for cars.

SH cannot patent tetris. They are a licensee, whose only required job
is to make sure that the original copyright owners (ELROG and the russian
guy) don't get their stuff in the public domain.  Nintendo also owns
a copyright on the modifications made to run Tetris on the Gameboy.
As such, only the original owners of the copyright can "try" to patent
Tetris, unless they want to sell that right (a patent or copyright is 
like any other asset that can be sold).

Fred is quite familiar with the legal issues here, as this is at least the
second go around on this issue for him (remember Ogre?)  Protecting the
intellectual roperty by means of which one earns a living is not "legal
bullying", but simply an attempt at survival in a very hostile environment,
the computer games market.

Not even close to a sufficient specification for the game.  You haven't
mentioned what controls are and are not available to the player.  You
haven't defined "full" for the container.  You haven't mentioned the
preview option.  You have said nothing about scoring.  You have said
nothing about early dropping.  You have said nothing about speeding
up motion as the score increases.  You have not identified the process
of "chewing back down" to fill in holes.

Tetris is an immensely subtle game; the millions of (wo)man hours being
lost to productive use world wide due to Tetris play occur because of
some excellent design choices, which is what makes the game design a
valuable (and legally defendable) intellectual property.

>   The various games that have come out, some on the Fish disks, follow

The legally defendable item is not the game code; the valuable intellectual
property is the game design.

>but are original works belonging to their authors and released to the

You have the wrong end of the stick.  Those authors were trying to deprive
SH of a valuable intellectual property, and the rest of us of a viable game
market.

Rubik's cube has a mechanical design which is quite ingenious.  However, the
more valuable part of the design is the intellectual thrust of the game.  I
once wrote a "software Rubik's cube" for my Apple ][+; it shared none of the
mechanical attributes of the cube, but all of its play aspects (except
"Rubik's Wrist"); had I released my code, I would have been violating the
intellectual property rights of Mr. Rubik.

>   Since SH cannot claim copyright infringement over the code, they are left

It is at this point worth mentioning that since you don't have a clue as to
what is being stolen in this case, your analysis is all wet.  The design of
a game is a separate, legally protectable entity, and that means the _play_
design, not the colors on the game board or, in this case, the screen.

>Their images have elaborate drawings as background,

Totally immaterial.

Irrelevant, and, since Tetris does not allow reflection, it has seven, not
five, separate playing pieces.

>significant, so one is left with a board determined solely by the game idea,
>which cannot be copyrighted.

The "game idea" can in fact be patented, not just copyrighted.  I have no
idea whether SH did so, but that is within their rights.

>Their situation is much the same as if someone
>copyrighted a drawing of a scene which included a 5x7 bitmap of an "M" and

Not at all.  The game idea, not the picture on the screen, is what is a
protectable object.

The game idea is exactly what can be protected, by fully legal means well
known and often used in the game design field.

>Taking on Fred Fish, whose lack of deep pockets is

Since Fred has long ago expressed in the clearest terms an insistance
on putting only legally distributable software into his much respected
collection, and since he immediately, voluntarily, and without grumbling
issued a recall notice when informed that the legal distributability of
the Tetris clones was in question, "taking on Fred Fish" is a loaded
phrase which has no relationship to the actual situation.  Neither is
it the case that protecting a valuable property is a "chaep hit"; it is
a way, the only way, to stay in the software games publishing business.

>It does not show the SH case holds any water at all.

SH doesn't have a "case", they have a property to which they have licensed
the rights.

Such an analysis would be pretty useless unless it also took into account
which play choices you had already made, in which case it would probably
make the game too easy.

I believe your statement comes under the heading of "misprison of a felony";
I sure wouldn't be sticking myself wallet first into this situation if I
were you.

Well, all of us with hopes of writing and distributing commercial software
naturally wish SH all the best, since if they fail it may well foreshadow
the end of the Amiga game/software market.

True.  Persons who value a strong Amiga games market, with lots of choices
on the shelves, would be well advised to buy an SH game or two just to help
them with the legal expenses needed to set a strong precedent here.

>3. Nastygrams to SH on the issue would not be inappropriate either.

Flames to twits who think everything in life should be provided to them
free of charge seem more appropriate.

As noted above, the Tetris game uses seven, since pieces without reflective
symmetry act as different pieces.

Sorry Kent, but you're wrong on this one.  BOTH the game code and the game
design can be protected: the first by copyright, the second one by patent.
So far, ELROG, the Russian author and Nintendo have used only copyrights
for protection (though I would assume a patent is being sought).

>Not at all.  The game idea, not the picture on the screen, is what is a
>protectable object.

Wrong again. Both are protectable (one with patent, the other one with 
copyright).  Note also another mistake you make later in your message,
when you imply that ideas can be copyrighted. Not so:

	IDEAS CANNOT BE COPYRIGHTED, THEY CAN ONLY BE PATENTED!

Just to fix a couple of inaccuraccies of an otherwise good response.

True, True. The Rubik's cube case was determined to be PATENT infringement
because of the way the patent claim was written-> Means+Function. i.e. his
patent covered any reasonable means to achive that functionality. The other
fellows mechanism was striken down as eqivilant means.  I have done 
a patent search and there are no US patents assigned to Spectrum Holobyte
covering Tetris.

Next possibility is trademark infrigement by the clones using Tetris like 
names. This is a legitimate beef if Tetris is a legally registered trademark
assigned to Spectrum Holobyte.  I was not able to determine this from my
search. The illegal use of the Tetris name in similar sounding names is
a very definate infringement of thier rights.

Next comes copyright infringement.  The key here is independent derivation
and the burden of proof is on Spectrum Holobyte.  You are allowed to 
reinvent the wheel as long as you don't use the same spokes.  Spectrum
Holobyte must prove that each author individually had access to and used
portions of their code.  This can include portions of disassembled code if
they can prove that the author had their executable and a disassembler and
they can find the code segment in the clone executable.  But the burden of
proof is on Spectrum Holobyte and their beef is with the authors not Fred.

If, as you say, Spectrum Holobyte is trampling on the non-infringing games,
then surely it is up to the author of each game to contact Spectrum Holobyte 
and assert *their* rights. Note that Fred being the main visible distributor
is the obvious target, but the games belong to the authors. I am no lawyer,
but it seems to me that even if Fred wanted to fight, he would need a lot of
help from the authors.

So, the bottom line is, urge your favorite author to contact Spectrum Holobyte
and assert their rights. Surely the authors have more at stake (and is much
more inclined) to arque that *their* game is non-infringing.

EVERHART@arisia.dnet.ge.com (Glenn Everhart 215 354 7610 (8*747 7610) GE Aerospace Technology) (06/14/90)

The short writing I attempted was intended to describe what I have
observed in several of the PD Tetris variants...not the SH game.
The details given recently indicate that there is significant variation
between the play of the SH game, which I have not seen, and the
variants which enjoy (?) rough similarity with it. 
   It is a principle of copyright law that expressions are copyrighted,
not ideas. Patents can protect ideas. (Incidentally, it turns out that
Rubik *LOST* a patent fight over the cube due to some prior patent on
a magnetically done cube. Surprised me!) The variants evidently used
only some of the game idea. That their results wound up looking similar
was a result of the geometry of tetrominoes and the nature of the
game idea. That should be sufficient to defeat any presumptions having
to do with similar appearance of the result. (How much of a clean room
does one require for a simple 2D drawing?) 
   In fact SH might well stress that its' game has properties that make
it a better playing game than a clone, and compete in that way. Rather,
it has chosen to use legal threats. Where legal threats are used to
remove independently developed programs from distribution, this bothers
me and creates what I regard as terrible precedents. (Note that there
are far less polite terms that could be used than 'legal threats' in
this case.) If a commercial offering can be replicated from a general
description of the idea in a few hours, I am also unbothered by the
notion that it will not long stand alone or survive. If the SH Tetris
game plays better than the variant tiling-with-tetrominoes games,
THAT is what they should stress. The visual appearance of the game
board is however too geometrically trivial. Any game built from my
crude description of the idea is going to look generally similar to it.
(This was the NEC defense in Intel vs. NEC if you recall.) 
   By the way, I do remember Ogre. When Fred withdrew disk 57, his
description of the affair was that that was HIS call; nobody hassled
him. Had he so chosen again, without hassling, this would not bother
me. As it is, I see yet another look 'n' feel issue, but the geometry
is so trivial that the point can be won for freedom of development.
   As for the names Tetris (and Tetrix possibly), the usual course
is to just rename something with a name that is causing trademark
grief. That's not what has been attempted. I see no point in regarding
SH's action towards Fred as a precedent on the issues, just as proving
that it can (alas) be done. Outfits like SH can be discouraged
from that sort of thing in one way: deny them any chance to make
money as a result of it.  Look 'n' feel lawsuits, and those who
threaten them or pursue them, are the enemies of cooperation and
progress in software. So, perhaps, are those who support them.

   Not even close to a sufficient specification for the game.  You haven't
   mentioned what controls are and are not available to the player.  You
   haven't defined "full" for the container.  You haven't mentioned the
   preview option.  You have said nothing about scoring.  You have said
   nothing about early dropping.  You have said nothing about speeding
   up motion as the score increases.  You have not identified the process
   of "chewing back down" to fill in holes.

Very little of that matters. As far as I can tell, he's missing two
things for describing the idea of the game (a spec can be copywritten;
an idea can't), and has some details he doesn't need. Let's try this:

	Tetrominoes enter a rectangular playing field at one edge, and
	move towards the other edge (game motion). The player is
	allowed to rotate the pieces in the plane and move them
	perpendicular to the game motion. When the blocks making up the
	tetrominoes fill the rectange from one perpendicular edge to the
	other, that line is removed and all lines towards the entry edge
	move to fill in the gap created. Object of the game: to keep the
	playing field from filling for as long as possible.

   Tetris is an immensely subtle game; the millions of (wo)man hours being
   lost to productive use world wide due to Tetris play occur because of
   some excellent design choices, which is what makes the game design a
   valuable (and legally defendable) intellectual property.

The game design - at the "look & feel" level - may be copyrightable.
The description at the "idea" level is not copyrightable. Many of the
things you mention would be independently invented from that
description by anyone knowledgeable in the field of computerized
games, which will make defending a copyright difficult. For instance,
the game getting faster; that's a common thing for arcade-style games
to do. Likewise, determining "full" must include something at the open
end of the rectangle, and exactly what that means will depend on how
tetrominoes are introduced onto the screen (which wasn't mentioned,
and doesn't need to be).  I've already seen variations on scoring; the
first version I saw didn't care how fast you put things down, but gave
points for deleting rows, with bonuses for deleting more than one row
at a time (let's see, I think it was 10 points/row, with an extra 10
points for every extra row deleted, so that a four-row deletion was 10
+ 20 + 30 + 40 = 100 points).

What hasn't been pointed out is that I could write a complete function
spec of the SH product, including direction, scoring, controls, and
anything else obvious to they eye (except "artwork"), and give that to
someone who hasn't seen the product to implement. The result would
_not_ be a copyright violation. At least, that's how the IBM BIOS
clone(s?) done that way were ruled.

   >   The various games that have come out, some on the Fish disks, follow

   The legally defendable item is not the game code; the valuable intellectual
   property is the game design.

The valuable intellectual property is indeed the game design; the
clearly legally defendable property is the code. Whether the "look &
feel" of the game is defendable is still being settled in the courts.
If it is, that would go a long way to covering the game design.

   >but are original works belonging to their authors and released to the
   >rest of us. SH is attempting to deprive these authors and their beneficiaries
   >(the rest of us) the benefits of their code.

   You have the wrong end of the stick.  Those authors were trying to deprive
   SH of a valuable intellectual property, and the rest of us of a viable game
   market.

No, he has his end of the stick, and you have yours. Both statements
are true. Which you see as worse is a religiouss argument.

   It is at this point worth mentioning that since you don't have a clue as to
   what is being stolen in this case, your analysis is all wet.  The design of
   a game is a separate, legally protectable entity, and that means the _play_
   design, not the colors on the game board or, in this case, the screen.

What is being copied isn't the question - that's clear to anyone. The
question is whether or not what is being copied is legally protected,
and whether or not it _should_ be.

   >It does not show the SH case holds any water at all.

   SH doesn't have a "case", they have a property to which they have licensed
   the rights.

SH doesn't have those rights until they get a court to state that they
have those rights when someone contests them. Of course, if no one
ever contests them, the do have them.

   I believe your statement comes under the heading of "misprison of a felony";
   I sure wouldn't be sticking myself wallet first into this situation if I
   were you.

Uh, "misprison" isn't a word. But it is valid to choose to contest
SH's claim that their "look & feel" is copyrightable. And that is
liable to be an expensive choice.

   Well, all of us with hopes of writing and distributing commercial software
   naturally wish SH all the best, since if they fail it may well foreshadow
   the end of the Amiga game/software market.

And, just as naturally, those of us who wish for that the best tools
be available wish anyone who would fight SH all the best, as their
winning their rights could well foreshadow the end of the
software/hardware clone market.

   True.  Persons who value a strong Amiga games market, with lots of choices
   on the shelves, would be well advised to buy an SH game or two just to help
   them with the legal expenses needed to set a strong precedent here.

And person who value a software market replete with lots of
rapidly-improving tools would do well to avoid any SH games, and to
purchase hardware & software from firm that is willing to market
clones and fight attempts to kill that market.

   >3. Nastygrams to SH on the issue would not be inappropriate either.

   Flames to twits who think everything in life should be provided to them
   free of charge seem more appropriate.

Yup. Especially those who think that just because they wrote the first
piece of software with a specific look and feel, they should never
have to face competition with that look and feel.

The Tetris trademark belongs to the soviet's ELORG.  Take a look at the

Not at all. One can claim "visual" copyright infringment and visuals can
be infringed with no access to source code.

The beef is with ANY author AND distributor of infringing software.   If
you read all the various legal software contracts, "distributor" is used
all over the place.  A distributor that willingly continues to distribute
software that is later proved to be infringed IS liable. So, IMHO, Fred
had no choice.

That assumption doesn't seem to be addressed one way or the other by the
available evidence.  Let me quote the relevant portion of Fred's posting
of Spectrum Holobyte's letter:

That is the SH president and not (necessarily) a lawyer.  I hope he's not
a lawyer, because he has mingled arguments for copyright infringement
with arguments for patent infringement, without even once mentioning the
words "copyright" *or* "patent".  He never states which rights he is
trying to protect, nor which rights are claimed to exist.  I get the
impression, in fact, that Mr. Adams either doesn't know, doesn't care,
or doesn't understand the difference.

	RE More Tetris Nonsense

	You can neither copyright *nor patent* ideas.  If you could patent
ideas, we'd have some rich SF authors floating around.  Bob Heinlen invented
the waterbed, the waldo, and a few other goodies in his stories; Arthur C.
Clarke invented geosynchronous satellites.

	I know a game designer who had to sit there and watch another company
publish a game 99% similar to his design.  His company could do NOTHING.

	In the case of a game, all that's protected is your EXACT, SPECIFIC
implementation of the game.  If it's something like a roleplaying game and
the other guy bumps all your numbers by 10%, you're pretty much screwed.
The specs for the game Tetris can't be protected.  They can cover the trade-
mark (Tetris) and keep other people from putting out versions with pictures
in the background and Russian music (does the Spectrum Holobyte version have
the music?  I forget.)

	Honestly, the real problem here is that the Spectrum Holobyte version
is a piece of crap.  They can't sell it because it's a bad program, not 
because PD versions have destroyed their market.  But they want to belive
the latter, it seems.

rains@dms.UUCP (Lyle Rains) (06/14/90)

  As someone within the games industry, I would like to add some other
information to this discussion.  As several people have pointed out, the
copyright laws protect the expression of ideas, rather than the idea
itself, but anyone close to a creative work knows the separation between
the expression and the idea can be extremely hazy.  At one extreme, the
designer might argue that the "idea" is to "survive as long as you can
and get as many points as you can within a set of rules," and claim that
the rules themselves as well as most other aspects of the game are an
expression of this basic idea.  On the other extreme, a programmer
implementing a PD copy of a game may feel justified that the general
screen appearance and rules of a game are the idea and only the code
is the expression (so as long as the code isn't copied, neither is the
game).

  Although there has not been a large amount of case history in the area
of games copyrights, there is enough to indicate that the courts are going
to take a view between those extremes.  The courts are willing to find that
there is intellectual property in a game design beyond the source code.
They will accept that the screen graphics are also protectable and that
within fuzzy limits, the entire game may be protected as an audio-visual
work like a motion picture or television program.  And just as in these
examples, the point where infringement begins can be quite hazy.  If you
made a weekly TV soap opera with good guys and bad guys and extra-marital
affairs and numerous sub-sub-plots, you could probably be quite safe.  But
if the series centered around the Texas oil industry and the bad guy was
slimely natural gas tycoon nicknamed J.J. who wore a black Stetson,
and the show was called "Fort Worth," you'd likely run into problems.

  In an old case involving a PACMAN(tm)-like game which was sold for the
Atari 2600(tm), the court found the the clone did indeed infringe, even though
the playfield layout had been somewhat altered and the animated characters
had been changed.  The court recognized this copy as an attempt to copy
the successful audio-visual work of the original PACMAN(tm) even though there
was no direct copying of code or screen graphics.  So within the industry, we
consider a game to be protected by copyrights on its source code, its screen
and character graphics, and as an entire audio-visual work.  But this is a
fairly young area of law, and definitive case law is scarce.  It is quite
possible that the courts may make new, conflicting decisions in the future
which would change the precedent upon which our industry currently depends.

  Even though the PD copies of games may seem harmless to most readers, the
industry has to protect their intellectual property, because if you end up
in a jury trial with a commercial copier, and he shows the jury that you
have not protected your property from the PD copiers, it can only hurt
your case.  The law doesn't see the income received by the copier as a basis
for infringement (though it may affect the damages awarded to the owner).
We regularly suffer from hardware/software/graphics copies of our arcade games
which come from Korea, Spain, and occasionally Italy.  The ability to invoke
our copyrights allows us to work with U.S. Customs and the FBI to help keep
flagrant copies out of the United States, but such protection is notoriously
hard to come by in Europe.

  From Fred Fish's earlier postings, it sounded to me like his exchanges
with Spectrum Holobyte had been professional, and that he understood their
position (whether or not he agreed with it) and was willing to withdraw
the PD Tetris' when SH gave him a clear written statement of their position.
Such things can rarely be "friendly" since the "hammer" is legal action, but
it didn't sound like brutal harassment by a big corporation over a little
guy.  And I do believe that SH was within their rights, and acted responsibly
to object to the PD versions of a product they had licensed and paid for with
royalties.

You must understand that Spectrum Holobyte is a VERY SMALL FISH in the now
gigantic struggle for the Tetris money.  There are already two lawsuits
involving Nintendo and a company owned by ATARI (yea, they're everywhere:-)
over the rights for Tetris.  SH is just one of the now many licensees of
Tetris.  Everybody knows that there are big bucks to be made on Tetris, mostly
because it is such an addictive game.  But one thing is clear, companies today
have no restraint to starting a lawsuit, if they have the minimal thought
that some of their rights might have been infringed.  As it was mentioned
before, a god account of the Tetris affair was published in last Friday
Wall Street Journal. You can find it at your local public library.

When somebody asked me what I thought of the letter that the SH representative
sent to Fred, I could only say that it was real "bogus" :-)  The guy seemed
to have little idea of the legal meaning of what he was talking about.  And 
that is unfortunate.

Tell that to Rivest, Shamir and Adleman :-) They'll tell you that you CAN
patent ideas (i.e. inventions). [see the details on my other reply to a
similar wrong assumptions by a fellow netter].  Get any recent book on
patents: they'll list the most recent decision on patentability of inventions
like the RSA crypto system, the Merril-Lynch Cash Management Program,
the Russian-English translation program, among many others.

I guess they were not interested in the often grusom, lenghty and COSTLY
process of applying for a patent.  All the items you mention certainly
would qualify as "patentable".

Sean, it is clear you absolutely know nothing about trademarks.  Changing
a letter doesn't make much difference, because trademark law ensures that
you are not trying to USE somebody else's name.  Clearly anybody reading
the name Tetrix will "associate" with "tetris" and that is enough for
trademark infringement.  

ELORG HAS a trademark on the name Tetris, and that can be enforced with ALL
other "similar" names for products of the same kind (i.e. computer games).

If Tetrix was the name of a lawnmower, that would be different, but Tetrix,
xtetris, textrix, and so on, do infringe on the Tetris trademark when used
to identify computer games.

Trademarks protect the "public association with the product name".  That is,
whenever a name can be associated with a "trademarked" one, there is possible
infringement.  Tetrix can clearly be associated with Tetris, and that is 
enough for infringment.

If you look at what I wrote above, "copyright" does not appear.  An idea
which is not "immediately evident to a knowledgable practitioner in the
field" or words to that effect, is patentable, with some other stipulations
about novelty and usefulness.  The idea which is patentable is that spec
that three of us have now attempted to write.  That, given the spec, any
competent programmer (even I) could write the game has no bearing on the 
patentability or defendability of the idea, any more than the fact that
any plastics company could manufacture them invalidated the patent on the
idea for the Hula Hoop.  Like lots of others, I've reverse engineered
games for my own amusement; that doesn't give me the right to distribute
them.

It would, however, violate a patent.  You're barking up the wrong tree.

The code is defendable under the copyright laws, but it is unlikely in
the extreme that the clones used the same code.  That is not the issue
here.  The patentability of game design does not need to be "settled
in the courts"; it is a legal principle of long standing.

There is no religious argument involved, merely a legal question.  That
question does not have two equally correct sides.

There is no question that the game design _can_ be legally protected; that
is a given: game designs are patentable.  I have not an iota of knowledge
whether such a patent actually exists for Tetris, nor have I heard anyone
else party to this discussion claim such knowledge.

When you start saying "should be", that is when you slide into religious
issues.  It is a fact of law that every civilized nation protects the
right of innovators to a fair return on their effort with a patent system.
Without such protection, Commodore would have had no motivation to create
the computer you are using to read this.  Game designers are not second
class citizens, and their rights to such protection are at least defendable;
without it, why bother to design games for sale?

Do you believe that you don't have the right to vote unless you go to court
to prove it?  It is about this point in your posting that you quit making
sense at all; was it very late at night for you?  Things further down are
not merely wrong, they are in many cases not even comprehensible.

>Uh, "misprison" isn't a word.

Well, if I had spelled it correctly it was, but I misused it in any case:

	"Misprision of felony (or treason); in common law, the offense of
	concealing knowledge of a felony (or treason) by one who has not
	participated or assisted in it." -- Webster's New Universal
	Unabridged Dictionary, 2nd ed., Simon & Schuster, 1983, page 1150.

The word I wanted was incitement rather than misprision.

"Look and feel" is not the issue, and confusing it with that issue, with
all the attendant baggage from recent controversies over the Apple versus
everybody on a design they stole from Xerox PARC in the first place, may be
what brought on the flood of illogic from you that follows.

This makes no sense at all; the words are English, the sense is gibberish.
Would you like to try again so we have some idea how you got from game
design to software tools in one giant leap across an abyss of non-causality?

Ditto, ditto, ditto.  The issues are not in any way related.  Are you well?

And ditto again; look and feel is not the question, game design is.

Really cheap shot from a mind in a blur; misspelled insults are hardly
impressive.

Who has certainly had better days.  Better luck next time, Mike.  Try
some coffee.  ;-)
