How do you spell
patent relief?
By Scott Bradner, Network World,

Patents, at least the way they
have affected modern telecommunications and business, have been very
controversial.
Patent advocates look to Section 8
of the U.S. Constitution and its adoption of the concept of patents to
"promote the Progress of Science and useful Arts."
Critics generally recognize the
importance, in theory, of the value of patents but assert that the current
patent system tends to stifle, rather than promote, the progress of useful
arts.
Starting last year, the U.S.
Supreme Court started an apparently careful effort to rebalance the current
system to bring it back to its original purpose. The focus initially was on
rebalancing the playing field between patent owners and users.
The question before the court more
recently, with a decision being announced in late April, concerned the balance
between those who wanted to get patent protection for their "inventions"
and those who contend that many of these "inventions" were just
obvious combinations of known technologies. The latest decision brought the
definition of "obvious" more in line with common sense.
There was a decision in another
patent-related case between Microsoft and AT&T that also was published in
April, but it hinged on a technicality that Congress could easily change, so is
not very important. There was a hint in one of the opinions that might become
important to the patentability of software, and that would be big indeed, but
it was only a hint.
The obviousness decision came in
the case of KSR International vs. Teleflex, and dealt with the patentability of
a type of pedal used in cars. The decision is a very important one, but exactly
how important will be determined by the special Federal Circuit Court that
deals with patents. This is the same court that this decision, as well as the
one a year ago, slaps upside the head to wake it up to the reason we have
patents.
In my mind, patents, when awarded
to real inventors, are an important driver of innovation. Many of the millions
of U.S. patents represent real innovation and were developments that made a
real difference, at least at the time. (Take a look at patents 5,183, 88,929,
224,329 and 2,292,387 for some examples -- Google patents is a good way to
search.) But far too many patents have been awarded that seem undeserved to
anyone in the field, or, indeed, to anyone with common sense. (See U.S. patent
5,443,036 for an example.)
Directly relevant to this column,
more than 100,000 patents have been issued that deal with the Internet in some
way. Many of them deal with using the Internet to make some existing process
work better. Many of those patents would not have been granted under this latest
ruling.
The ruling says "if a
technique has been used to improve one device, and a person of ordinary skill
in the art would recognize that it would improve similar devices in the same
way, using the technique is obvious unless its actual application is beyond his
or her skill."
Thus, the first person to use the
Internet to improve an existing process might have deserved a patent (although
I doubt it); many of the others would not have since "a person of ordinary
skill in the art" (a key patent concept) would have found it obvious to
use the Internet to improve other processes.
Until this decision, the courts
had limited the learning to the exact problem trying to be solved. For example,
using the Internet to order pepperoni pizza would only have been obvious if
someone was already using the Internet to order anchovy pizza, but not if
someone were using the Internet to order Chinese food.
The decision recognized that
granting patents for obvious work inhibits innovation and can destroy the value
of existing patents: "Granting patent protection to advances that would
occur in the ordinary course without real innovation retards progress and may,
in the case of patents combining previously known elements, deprive prior
inventions of their value or utility."
Also from the decision: "We
build and create by bringing to the tangible and palpable reality around us new
works based on instinct, simple logic, ordinary inferences, extraordinary ideas
and sometimes even genius. These advances, once part of our shared knowledge,
define a new threshold from which innovation starts once more. And as progress
beginning from higher levels of achievement is expected in the normal course,
the results of ordinary innovation are not the subject of exclusive rights
under the patent laws. Were it otherwise patents might stifle, rather than
promote, the progress of useful arts."
This decision is one that will
cause confusion about the validity of perhaps hundreds of thousands of patents,
block the granting of many of the patents currently in process, and maybe stop
some people with dubious patents from suing others for infringement. But it
will also provide lots of work for people like me who sometimes work as expert
witnesses in patent cases and it will, in my opinion, make the patent system
stronger (after all of the bugs are worked out and if Congress does not mess
things up too badly with patent "reform.")
Disclaimer: I'm sure that parts of
the university have strong views on patents, but I did not ask them about this
column, so it is my own opinion.
