Apple Patent Blocking PNG Development 357
Daniel writes: "Apple has a patent (U.S. Patent No. 5,379,129) on compositing a source and destination image using a mask image. This patent appears to read on alpha channel transparency, which the PNG and MNG file formats use. APPLE has declared in their patent statement to the Scalable Vector Graphics Working Group that their patent is only available for RAND Licensing. Since this patent appears to read on the PNG file format, Apple is hampering work on the PNG and MNG file formats.
Perhaps Apple would like to clarify this situation by explicitly stating that this patent does not cover the PNG and MNG file formats or by RF Licensing their patent to the PNG and MNG development groups.
Alternatively, the PNG and MNG developers are asking people to submit prior art in order to invalidate Apple's patent. SGI in particular appears to have prior art with their 'blendfunction.' Make sure the prior art you submit is older than May 08, 1992, the filing date of Apple's patent."

This type of behavior needs to stop. Now. Think different. Indeed!
I know that a lot of people here are excited about Apple's use of Darwin/*BSD in MacOSX. I think this is invalid. Apple couldn't build their own OS so they use choose *BSD to gain market share.
There really isn't anything wrong with this. It was a logical decision on their part. I just wanted to point out that this in NO way invalidates there bad, unfair, and rude behavior.
...Remember that corporations are amoral. Not moral or immoral but amoral. They logically determine how to make the most money. They make decisionswithout regard to compassion or ethics, much like a computer.
This explains the BSD decision but this also explains the RAND decision.
Unless we stand up an say NO this behavior will continue.

I for one am extremely outraged. I'm sick of this shit. I'm sick of being pushed around by corps. Might makes right. It sickens me that I cannot in good faith buy from virtually any company. I don't want my money paying for this bullying. This ranting does nothing though. Apple's betting most people won't care and they're probably right. Heck how many people have the balls to even boycott RIAA member record companies? How many people have the balls to reject bullshit dvd's? Not that boycotting them makes any difference whatsoever. But how much of your money has gone toward buying politians? How much has gone toward bullying PNG? Some of the money is mine. It makes me sick. I buy this shit anymore. Even one of my favorite bands, the anti-establishment, anti-big record comany, anti-MTV NOFX, has a lead singer who started an RIAA member record company. How can I justify purchasing from them any longer? Thank you. I'll go back to my cave now.

Have you read this [w3.org] linked page? Have you read any statements made by Apple that they are using this patent to prevent you from using the PNG format?
If you look at that page, you will see that Apple does offer a license for the patent as part of the SVG 1.0 patent which is being put together. It looks like they are just being cautious in order to keep their rights to the patent intact, but still allow it to be used for PNG and SVG.There are plenty of greedy corporations out there and Apple may in fact be one, but don't assume they are without looking at all the facts. Take a look at the sites listed in this article, write to Apple and ask questions, express your thoughts to Apple. If you are not then satisfied with what you see then you can make as much noise about it as you want. Making a big deal about this just because someone has implied wrongdoing on Apple's part is just being a follower.

Apple Advertises '1-click' licensing. goes more toward proving amazon.com suckered them than showing evil on their part, and on Apple sues to stop leaks. I emphatically support their action, although you probably didn't get the complete story unless you read some real news on it. Apple tracked down and stopped a leak in their R&D division. He was trying to be harmless, releasing roadmaps and product details to Mac rumor sites, but his actions certainly gave Apple a huge disadvantage and lost them money. All they did was get him to agree to stop, even though they certainly could have won monetary damages. How can you oppose that?
"...a lot of us contribute to Apple. Hint. Stop posting Apple press releases on slashdot. :)" Oh yes, Apple would be davasted if /. stopped doing mostly misinformed and negative reports on their products. "Think different. Indeed!" Interesting since half your complaints had to do with people "Thinking Same." "Apple couldn't build their own OS so they use choose *BSD to gain market share." Apple can't make their own OS, eh? Actually they scrapped years of work to go with the BSD core, and they managed to put an interface on it better by orders of magnitude than anything yet available for an OSS OS, not to bash OSS OSs of course, just saying UI and setup is their big weak point in the desktop world currently. But I'm pretty sure everyone already realizes that "Apple couldn't build their own OS" was a troll.

Ignoring the whole "give away" and "intellectual property" parts of it, I'll point out that they aren't being asked to give away anything. They're being asked to stop trying to take something that doesn't belong to them. The idea was not their's, nor was it or its use exclusive to them. The purpose of patents was to encourage ideas, not direct money to big buisness who can afford to file dozens of supirious patents.

Patenting things which are prior art is also detrimental to capitalism, since it increases the risk of lawsuits if not actual damages and limits genuine innovation. *Bogus* patents are antithetical to "making money" in both the short and long term, unless you're a lawyer.

Actually, Alvy Ray Smith with Ed Catmull created an alpha compositing system in 1978 while Ed Catmull was doing a paper for SIGGRAPH '78.
He states this in his paper "Alpha and the History of Digital Compositing" in August 1995.
He says that his earliest dated documentation he has for that code is dated January 13, 1978. He specifically showed compositing an alpha image on a background which should just be like another image. I hope this helps

Did you ever stop to think that patents are a way for companies to avoid competition? To keep out the little guy?
Many companies have decided that instead of competing on price and quality, they would rather go to the govt. and get an exclusive monopoly to use a certain technology. Because the pace of change in the tech field is so rapid, patents are effectively eternal. And when people criticize this, because they want to see competing products in the marketplace, you call them communists?

If no one implemented alpha channels in PNG, it would not be an issue, even though PNG is capable of storing them, and it would look bad. Several other formats implement alpha channels, and so this does not apply to them directly either, only to the mechanisms which use it to do *compositing*.

7. A method as in claim 1 wherein said method produces anti-aliased text in said destination image by performing the method with the
source image being a pattern and the mask image being anti-aliased text.
(Claim 1 is the basic alpha-transparency concept).
Suppose that someone comes up with prior art that invalidates claim 1. Apple can still claim rights over the use of this technique for anti-aliased text unless someone can show prior art which covers that specific application. So don't just look for prior descriptions of alpha-transparency: look for prior use of alpha transparency for text, and anything else in the claims.

It was well known that de-facto standard for file compression in the net, "compress", was covered by the Unisys compression patent. However, showed no interest in enforcing the patent outside hardware (modems and the like), and would informally tell people who asked that.
Nonetheless the FSF insisted on having a patent free compression format for use by GNU, and eventually settled on gzip. This made some people angry, it was annoying to have to deal with a new compression format, and they claimed the FSF was seeing ghosts and that Unisys would never change their policy.
However, as we all know, Unisys *did* change their policy, allthough the target wasn't compress (which meanwhile had lost most of its markedshare to gzip), but GIF which used the same algorithm internally, and had become a big thing thanks to the WWW. Thankfully, at that time we had gzip, and could create PNG fast using the same code.
The morale "they haven't enforced the patent yet" provide false security. Companies don't enforce software patents until it become economically profitable to do so, typically when the algorithm is in so common use that it will be expensive to switch to an alternative. What we need is a legally binding promise not to enforce the patent.

This patent is only good for toilet paper.
Patents are granted by the patent office. They are not Valid until tested in a law court. It is not the patent office's job to determine whether there is prior art. If they know there is, then they will not grant the patent. If they are not certain then they will grant and wait for someone else to challenge (no sense in wasting taxpayer's money).
As others have said, Apple have to maximise the shareholder value or the directors might go to jail. So even if they are certain that there is prior art, they will still file a patent - after all, it may be that no one bothers to challenge. Then, when it turns out Apple accidentally infringes some other, equally worthless, patent, they can do a mutual exchange. The shareholders will be impressed, and the potential for lawsuits reduced.
This is considered sound business practice in the USA.
It may be seen in a different light by the rest of the world, but WTF.

This argument is raised every time there is a patent dispute discussed on slashdot yet I'm always a little uncomfortable with it. We say something is "obvious" but we say so many years after it was invented (perhaps) and patented; years during which we have used it and become familiar with the concept. Was it really obvious when it was developed and patented or has it only become "obvious" because of it's subsequent widespread use and our consequent familialarity with the concepts involved?
In this particular case I suspect that the concept was indeed obvious by 1992 when the patent was issued - that seems pretty late in the game for such a basic concept in computer graphics. If it was obvious it won't be hard to find prior art. But in general we should recognise that concepts that are obvious to us now after long use were often breakthrough innovations obvious to no one when they were first developed.

Apple took out patent: Nerds are outraged! (Score:2, Insightful)
(Of course, it is perfectly legal to take out a patent, but don't let that stop you from throwing a tizzy fit.
Yes I know, slashdotters view software patents like Microsoft views the GPL (of course Microsoft is wrong, but that doesn't stop them either). But before the Great Slashdot Hornet Swarm decends en masse on poor Apple, I'd like to point a few things out:
1) The patent dates back to 1992. According to O'Reilly's "Web Design in a Nutshell", PNG only dates back to January-February 1995. You'd think that if someone was starting a new graphics file format on which the future of the web depended, they'd check around for patents they might be violating first. Seems like common sense to me, especially since they are billing the format as "patent free".
2) None of the links in the parent posting pointed to anything that explicitly stated that Apple was refusing to license its patented technology to PNG or sending them cease and desist orders. I could not find anything on Google or on Apple's web site to support this. What I did find was this statement at "http://www.apple.com/about/w3c/" (part of Apple's statement in support of royalty free W3C standards:
"While the current draft patent policy does state a "preference" for
royalty-free standards, the ready availability of a RAND option
presents too easy an alternative for owners of intellectual property
who may seek to use the standardization process to control access to
fundamental Web standards. A mandatory royalty-free requirement for
all adopted standards will avoid this result."
One of the links on the Slashdot parent post did refer to lots of companies getting royalty free licensing for this patent. So all the PNG folks need to do, if they haven't already, is ask Apple nicely for their royalty free licensing option, since they are a web file format. End of problem.
3) I know you all really, really hate Apple. But if you are going to make them look evil, you are going to have to try a lot harder next time.
