I see a bit of confusion by some in that they seem to think that these patents somehow only apply to streaming video. This is not the case.

The first five patents listed at http://www.acaciaresearch.com/dmt/dm...tlpatents.html are the subject of contention and they are all related, in that the later patents are continuations of the earliest, 5,132,992. I guess you can look at Patent No. 6,144,702 as the final elaboration/description of the invention they claim is theirs. But, since that is (within the "Parent Case Text" of the patent) based on the earlier four, we have an effective filing date of Jan. 7, 1991.

(This means prior art searches must be done within publications before 1991, instead of 1992, which I mistakenly gave earlier.)

So, we have to consider the "claims" of patent # 6,144,702 to see what sort of invention they say we're infringing. It's within the "claims" that the specifics of how the invention accomplishes what it says it does that give the patent vadility. You can't patent an idea or concept of a machine that sews clothes, but a specific arrangement of gears, cogs and levers used for sewing clothes can be.

There are 42 claims within patent # 6,144,702, but they boil down to this:[list=1][*]a way of storing compressed, digitized media [*]in a library that has a listing of the offerings[*]which is used to choose a selection[*]for download and viewing by users of the system.[/list=1]

That's a basic (probably too basic, I'm still working on it and would appreciate feedback) cliff notes version of the claims. And, it certainly describes how we use video files on our sites, whether streamed or not.

what year did .FLI and .GL (not sure about this format) video files start showing up on BBS systems?

And don't forget the good old ANIM files on the amiga BBS's! Now, if there's just a manual out there that describes how they were used back then...

I wonder if usenet qualifies as published material.

I'm sure it does.

Anyway let's stop talking about possible prior art in the public forums....

The IMPA guys have said it a few times already... anything we discuss here in the open in regards to prior art will most likely be seen by Acacia & the more they know about what the IMPA is going to hit them with, the more they can prepare for it.

Translation?

Send anything you find to spike at homegrownvideo.com and he will make sure it gets to whoever it needs to get to.

fiveyes

Oh, yes, indeed there is!

And if there's just one operational manual, printed instructions or even publically available correspondence that described the claims (before 1991!), it might be valid prior art.

One word bro...

"GIF89" was capable of streaming video all the way back in 1989... it's a compressed format that allowed for indexing of videos -- ie: Compuserve (the inventor) and any number of BBS's... They were at least 2 years too late.

TheFLY

.FLI and .GL was my last year of middleschool so it was at 1990 if not earlier

gothweb

Prior art should be easy. I just hope someone shows it before all us little guys get to court. IMPAI should push for an early trial date, and end this crap now.

Here we go... .GL was the Grasp format...

"GRASP was originally created by Microtext Incorporated of Irvine, CA. It was bought in 1988 by Paul Mace software, where it is maintained today. Information on GRASP and GRASP Multimedia may be obtained directly from Paul Mace Software: "

1988 baby... KISS MY ASS

They got nothing... We could get even more oldschool if we started talking about Amiga... and this is just public domain software -- we're not even talking about what companies like IBM were working on back then... or universities... Probably if you go to the library and look up the really old periodicals on computer graphics research you will find prior art all the way into the early 80's...

gothweb

Was .GL (grasp) compressed?

Earlier... 1988

"The Moving Picture Coding Experts Group was established with the mandate to develop standards for coded representation of moving pictures, audio and their combination. Starting from its first meeting in May 1988 when 25 experts participated, MPEG has grown to become an unusually large committee. Usually some 350 experts from some 200 companies and organizations from about 20 countries take part in MPEG meetings. As a rule, MPEG meets three times a year (in March, July and November) but meets more frequently when the workload so demands."

Hey TheFly. So good of you to tell Acacia everything we've got. It's a damn good thing your weren't a reporter in Iraq or none of our troops would be coming home alive.

fiveyes

Not that simple, unfortunately. Knowing that digitized, compressed media has been around for awhile doesn't help. What matters is knowing and understanding the claims of the patent(s) in question, and finding a document which was published before filing that basically describes the invention or from which the invention could be obviously implemented.

Here's a link to what constitutes "prior art" and where to look for it:
http://web.archive.org/web/200206112...rttutorial.htm

Oh, and a reminder that specific examples should not be posted! Send them along to spike at homegrownvideo.com and he'll be certain that they're properly reviewed by the experts.

I think you overestimate the usefulness of my information...

Right now I'm researching video compression patents -- I'll post anything useful if I find it.

SoBeGirl Video

I still say that if you serve MPG files you will be better off and maybe safer from litigation.

It might be a challenge for those who have plug-In feeds such as I do at http://www.sobecams.com to stay in business.

Becuase if webmasters agree that it is better to serve only MPG files they may be apt to cancel subscriptions with the plug-In feeds they are using.

I know that SoBeCams lost a few customers to SoBeGirl becuase SoBeGirl sold them 200 content sets for 1200 bucks.

And if you couple these great video content deals with the fact, or opinion, that the MPG file is not a streaming file format becuase it is a downloadable format you may just cancel that feed and buy a bunch of MPGs.
