Baase §4.7
Do patents help advance progress? or hinder it?
Patents are pretty clearly a market
regulation
with the sole goal of improving innovation in technology. Inventors
don't "deserve" to profit from their ideas; we simply want to make sure
they are motivated to continue. In other words, this is purely
utilitarian.
Patents are intended to cover INVENTIONS rather than IDEAS. If you have an idea to sell hamburgers with salsa, or newspapers & beer together, or to create a website where people can post their own stuff, that's an IDEA. It can't be protected: everyone else is entitled to copy it freely.
Richard
Stallman on Patents, 2002
Stallman is against software patents, of course. However, his case is
better than many open-source-related arguments; in fact, it is squarely
aligned with the interests of software-development businesses.
My (former) three-part test on when it is appropriate to recognize software patents:
35 U.S.C. §101 (patent-eligibility law):
Whoever invents or discovers any new and useful process, machine,
manufacture, or composition of matter, or any new and useful
improvement thereof, may obtain a patent therefor, subject to the
conditions and requirements of this title.
The meaning of "process" is critical here: does it mean any procedure or method? Or does it
mean "industrial process"? Historically, it pretty clearly was intended
to mean the latter.
Pharmaceutical patents are sort of the poster child for Why Patents Are Good For Us. Here the patent system IS effective at encouraging investment:
One weirdness: patents "for the use of";
someone can, if drug X is in the public domain, patent
the use of X to treat disease Y (this must be in some legal sense a
"new" use of X).
In practice this is not
much of a problem, because generic manufacturers can still make and
market X for its old purpose, and doctors can prescribe it for its new
purpose. Such prescriptions are sometimes said to be "off-label"; they
are an important way for drugs to get to people who will probably be
helped by them, but for which no company has yet done clinical trials,
and never will.
Some specific drugs:
cancer monoclonal-antibody drugs
These protein compoundss are antibodies that are highly specific to a
certain substrate; they have very narrow targets. From http://en.wikipedia.org/wiki/History_of_cancer_chemotherapy:
Another branch in targeted therapy is the increasing use of monoclonal antibodies in cancer therapy. Although monoclonal antibodies (immune proteins which can be selected to precisely bind to almost any target) have been around for decades, they were derived from mice and did not function particularly well when administered to humans, causing allergic reactions and being rapidly removed from circulation. "Humanization" of these antibodies (genetically transforming them to be as similar to a human antibody as possible) has allowed the creation of a new family of highly effective humanized monoclonal antibodies. Rituximab, a drug used to treat lymphomas, is a prime example. -- Wikipedia
The
point is
that some cancers can be specifically targeted by certain antibodies,
because they have specific antibody receptors not present in
non-cancerous cells. The receptors involved tend to be very
idiosyncratic.
None of
these drugs would exist in the US marketplace if it were not for
pharmaceutical patents.
On the other hand, the US Food and Drug Administration, which
regulates new drugs, is arguably a massive government intrusion into
the free market. Why shouldn't patent law intrude as well?
imatinib/gleevec: leukemias,
stomach cancers. It is used to treat cancers where the cells involved
have a specific receptor. Time magazine called it the "magic bullet
against cancer" in 2001, when it was approved, though that was an
overbroad assessment. It was also the subject of a patent lawsuit in
India in 2007; the case was referred by the Madras High Court to the
WTO.
rituximab/rituxan: binds to the WBC surface protein CD20. Used to treat leukemias/lymphonmas, also some autoimmune diseases such as lupus
cetuximab/erbitux: metastatic colorectal cancer, head&neck cancers. Binds to EGFR receptor; it is an EGFR-inhibitor.
trastuzumab/herceptin:
breast cancer. Monoclonal antibody that interferes with HER2/neu
receptor. In some breast cancers, the HER2 receptor is, as wikipedia
put it, "stuck in the 'on' position".
Antibiotics
nobody makes these, actually. The FDA requires not just proof of
effectiveness, but proof that the infection that was cured was in fact
resistant to existing antibiotics. This makes clinical trials very expensive.
Protein pump inhibitors
(PPIs): used for various stomach-acid problems, including ulcers
omeprazole/prilosec
lansoprazole/prevacid
esomeprazol/nexium
HIV: protease inhibitors moved HIV from a short-term acute illness
to a long-term chronic illness. This made drug development profitable
again. When AZT
(one of the first effective anti-HIV drugs) was first applied in the
early 1990's to HIV patients, though, it was an off-label use.
red/white-blood cell drugs:
filGRAStim/neupogen
makes more neutrophils/other WBCs. Used for cancer/chemo/BMT patients
erythropoietin
makes more RBCs: kidney disease, cancer, cancer treatment
diabetes
exENatide/byetta: this often means the patient can
avoid taking insulin. It is offcially for type-2 (non-insulin
dependent) diabetes. From byetta.com: Byetta
may also be used for other purposes not listed in this medication guide.
In 1984, Congress passed the Drug
Price Competition and Patent Term Restoration Act, also known as
the Hatch-Waxman Act. This allowed generic drug makers to use a patented
drug in their own
FDA application, so that approval would be in place as soon as the
original patent expired (normally after 20 years). However, it also
gave pharmaceutical developers a chance at a patent extension for up to five extra years,
subject to the following:
Basically, if a country is too poor to afford to treat all its
citizens with a new drug, many may die. This has definitely been the
case with some HIV drugs. As a result, the Third World has long argued
that it should be exempt from pharmaceutical patents.
In the mid-1990's, the WTO basically agreed, and allowed (I'm not
sure of the exact terms) third-world countries to manufacture generic
equivalents of first-world drugs for use within their own borders only.
The manufacturing must be for the government's own use (eg in
distributing to its people; the manufacturing can't be a for-profit
initiative of a private company in that country). Also, a good-faith
attempt must have been made first to negotiate for a reduced-rate
license to manufacture the drug, and such profits as are made must be
given to the patent holder. In practice, large US pharmaceutical
companies often enter into vastly-reduced-price licensing arrangements
with third-world companies.
In 2005, the WTO relaxed this rule to allow poorer nations to import generics that would otherwise be covered by a patent. This is sometimes described as a "compulsory license". The manufacturer would not be prosecuted.
This is perhaps the foremost third-world patent issue.A classic "broad" patent is the Wright brothers patent on "wing-warping" to control flight (to the Wrights, the wings were the "aero-planes", planing the air, the rest of it was the "flying machine"). The Wright brothers actually twisted the whole biplane structure -- using cables -- to bank in a turn. This later led to the development by others of ailerons, which achieve the same effect but which mechanically are entirely different. A court ruled the Wright patent still applied: what mattered was the concept of adjusting wing angles to tilt the craft.
This is a classic "broad patent" for a major new innovation. The
courts have traditionally recognized "broad" patents, but somehow in
software this distinction is often lost.
History of software patents
For a long time, software was held to be unpatentable,
as mathematical algorithms are unpatentable. Any fundamental
mathematical or physical laws are unpatentable.
1972: Gottschalk v Benson (wikipedia): You can't patent a mathematical algorithm (in this case a number-format-conversion algorithm). More below.
1973: ATT somehow manages to patent the setuid bit, claiming it's
hardware. This patent was dedicated to the public domain in 1979. This
patent is certainly a deep idea: if a certain bit is set in the
filesystem information node for a file (not in the file itself), then
when the file is executed,
it runs with the privileges of its owner and not the user. Before then
(and after; see what Windows does), there were complex ad-hoc methods
for running selected programs with elevated (or alternative) privileges.
1981: Diamond v Diehr: computer + machine IS patentable. For a
long time after, software patents always described the software in
combination with some hardware device. This patent dealt with the
curing of rubber, using a computer to guide the process.
Diamond v Diehr: SCOTUS says that an invention isn't automatically unpatentable just because it contains an algorithm But PTO & lower courts read in the converse: algorithms are patentable
Note that the current business-world baseline thus rests on USPTO policy and lower-court case law, NOT congress or SCOTUS.
Problem of "non-obviousness" the rules state that it's not enough to prove it's obvious today. Uh oh. That becomes an extremely difficult burden.
To be patentable, an invention must be "novel". Novelty is usually
challenged by the presentation of "prior art":
did someone else discover it first? Often there are arguments about
this.
If prior art is published,
it can invalidate a patent. However, if it was used privately, those
users can continue to use their idea without paying royalties to the
owner of the patent, but the patent may still stand. The patent can be challenged on the grounds of
not being novel, but this is harder.
Broad patents for fundamental new ideas, narrow patents for improvements
compatibility issues: What if the default, standard implementation
is patented? Two cases where there was at least some movement away from a
patented format:
GIF => PNG
MP3 => ogg vorbis
software patent v copyright
Supreme-court cases limit the word "process" in USC Title 35, Chapter
10, §101:
Inventions Patentable: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Here the "process" claim is so abstract and sweeping as to cover both known and unknown uses of the BCD to pure binary conversion. The end use may (1) vary from the operation of a train to verification of drivers' licenses to researching the law books for precedents and (2) be performed through any existing machinery or future-devised machinery or without any apparatus.
Applications of computer algorithms may indeed be general. In retrospect, should this be an issue? The end-uses above are all for software using the algorithm; and anyone could always use a different algorithm.

Here's an interesting list of some software patents, supposedly
"random" though some particularly famous ones are sprinkled in:
http://bat8.inria.fr/~lang/hotlist/free/licence/patents.html
Another list can be found at: http://www.textfiles.com/law/softpat.txt
xor cursor, patent 4197590 (below)
Method for dynamically
viewing image elements stored in a random access
memory array
cpu Stack Pointer register, patent 3794980, to George Cogar,
1971. Supposedly, though I can't find the source, this was purchased by
DEC [?] and eventually placed in the public domain. Or not enforced. Or, possibly, it was in fact licensed by Intel/motorola/everyone_else.
ATT setuid-bit patent, # 4135240, invented by Dennis Ritchie,
applied for in 1972 and later placed by AT&T in the public domain.
Using an xml document to describe the grammar of another xml document (Part of Scientigo's patent suite on xml)
British Telecom patent on the hyperlink, files 1976, granted 1989.
Patent number 4,873,662. In 2000 they attempted to sue a large number
of websites. The
patent itself apparently refers to a system in which multiple remote
users can access "blocks" of data on a central computer.
Altavista patents on "web searching". Altavista did have several
such patents on basic web "crawling". Most were predated by the
"archie" archive-searcher for ftp sites, developed by Alan Emtage in
1989. Altavista was purchased by CMGI, which some claim is a patent
troll.
RSA encryption: patent 4405829
RSA uses standard high-precision arithmetic in its calculations; the underlying number theory has been well-known for centuries. The patent was for the APPLICATION of these standard methods to encryption. That application was certainly novel.
The RSA patents finally expired, after much controversy. Part of
that controversy was self-induced; the patent owner at one point appeared to grant a general license
for noncommercial use, but then backed away from that.
Compton 1989 patent on multimedia, despite Apple Hypercard in ~1987.
Steir's patent 5,060,171 on artificially adding hair to a person's image [Garfinkel article]
Eolas v Microsoft:
About a way for running "applets" in a browser window. See below.
NTP v RIM: the blackberry patent
mp3: lots of development went into this
Lempel-Ziv / LZW compression, patents 4464650 [?], 4558302
This is the compression scheme in GIF file formats. The gif format was
developed by CompuServe in 1987. A year later, they noticed that the
algorithm was patented, and that the patent was currently held by
Unisys. Allegedly, Unisys told Compuserve at that time that they would
not need to pay royalties.
In 1999, Unisys demanded that some noncommercial websites pay a
$5000 fee for hosting files in the gif format (an interesting strategy,
given that the sites were not themselves rendering the images). Some
commercial sites
were asked for even more. It's not clear whether anyone paid it; most
affected sites rapidly switched to .jpeg or .png. Some observers were
especially offended by the fact that Unisys allowed the use of the GIF
format as a free standard until it became well-established, and then demanded fees.
There's some question as to whether this was the only or even the
dominant reason for the shift to PNG format; the latter does offer more
features (especially alpha and gamma) than GIF, and is a lossless
format unlike JPEG.
Natural-order recalculation in spreadsheets:
More below.
Rene K. Pardo and Remy Landau filed for a patent in 1971: U.S. Patent 4,398,249. This was an important case in allowing software patents (initially their request was denied as an "algorithm")
Spreadsheets were a brilliant idea (Dan Bricklin, VisiCalc?), but not order of recalculation.
MS has patented the FAT disk format. Here is a summary of the
events from the Public Patent Foundation, which had challenged that
patent:
The fact that PubPat can't appeal or even respond to the decision is
a serious due-process issue. If you are sued by Microsoft for using the
FAT format, you will be allowed to respond to Microsoft's post-2004 amendments to the patent claims. But you will probably not.
Microsoft is now actively licensing the format to flash-card manufacturers. Why not switch to the free ext2 filesystem? Because that just is impossible, that's why.
It is unclear which patents Microsoft is most interested in pushing.
While there are legitimate reasons for thinking that FAT itself might
not be patentable, Microsoft later introduced a strategy for supporting
both long filenames and also "8.3" filenames (8 char name, 3 char
extension). The patent that covers the dual-name strategyis less vulnerable to "obviousness" or "prior art" challenges.
Microsoft sued the TomTom people (http://arstechnica.com/microsoft/news/2009/02/microsoft-sues-tomtom-over-fat-patents-in-linux-based-device.ars), because TomToms, although they are based on linux, use the FAT filesystem internally. The suit was settled two months later, after TomTom agreed to cut the FAT.
FAT is a good example of an idea that is obvious to anyone presented with the problem of how to create a simple filesystem suitable for small devices. However, there is the added problem of it's being standard (although an unofficial one); you can't just implement a workaround.
A few compatibility issues where a patented file format (or
file-creation algorithm) has led to a new non-patented standard:
GIF => PNG
MP3 => ogg vorbis
PTO (Patent & Trademark Office) problems:
ignorance is no defense: "submarine" patents
The entire process is secret: you can be making good-faith effort
to be noninfringing and get hit with a huge verdict.
Infringement is considered willful if you had advance notice of infringing. Your belief that the patent was invalid is NOT a defense. Damages automatically triple.
Three groups of stakeholders:
Where do we fit in?
How large corporations manage:
small inventors:
Open source: voip
Legal advantage of small inventor: somewhat diminished with rise in legal fees & increased ambiguity
But small inventors can still sell to patent-holding companies.
Legal situation of large corporations:
Eolas v Microsoft
Patent 5838906: Distributed
hypermedia method for automatically invoking external
application providing interaction and display of embedded objects
within a hypermedia document, filed in 1994.
The alleged invention is about a way for running "applets" in a
browser window.
Is this really an "invention" at all?
Back in 1992, browsers just displayed images and static text.
However, it was clear by then that applications could display content in
windows created and "owned" by other applications; for example, MS Word
could at that time display an Excel subwindow.
What was not foreseen was that browsers would become universal
viewers of just about everything.
Microsoft v Eolas (+ Univ of California, as part of UCSF):
MS lost this case in 2004; was ordered to pay $521 million.
They then won the right to a new trial, but settled in 2007 before the
beginning of the new trial.
Patent covers
Patent filed 1994, granted 1998, USPTO review 2004, upheld 2005
See http://cse.stanford.edu/class/cs201/projects-99-00/software-patents/hypermedia.html
"Viola" prior art: may or may not be relevant: see http://www.viola.org
The Viola browser project was found by the district court to have been "abandoned", but the circuit court found that Viola version 1.0 was "abandoned" only in the sense that it was replaced with version 2.0.
Part of the technical issue was about the meaning of the term "executable application". The court allegedly gave this broad meaning. Microsoft claimed it only meant "standalone applications".
Eolas started by Michael Doyle, faculty member of UCSF.
UC Berkeley is apparently the owner of the patent.
Doyle certainly had some early ideas, that came before Java applets.
Had the Eolas patent been more aggressively enforced, it would have
been a huge impediment to the world-wide web.
2007: MS has claim they
invented it; this loses in Sept,
but Eolas & MS settle in August
October 2009: Eolas has launched a major lawsuit against just about
everyone: press
release. The list of defendants includes lots of sites that use
web-embedded objects: amazon, apple, eBay, and youtube.
View 1: Eolas developed some early web-embedding technology, and got
really lucky
View 2: Eolas patented Microsoft's 1990 Object Linking and Embedding
idea, and got a 20-year license to fleece us
View 3: Eolas may control a "critical" piece of the web standards.
We will return to this in a bit.
