Group Attacks Bad Software Patents Before They're Approved

Curupira writes "Ars Technica discusses how the Linux Defenders group are exercising the rights granted by the America Invents Act to identify and fight the patents that potentially threaten Linux and open source software. From the article: 'In a session at LinuxCon today, Linux Defenders director Andrea Casillas explained how the group is using rights granted by the new law to fight patent applications. A project of the Open Invention Network, Software Freedom Law Center, and Linux Foundation, Linux Defenders examines the 6,000 new patent applications published each week, attempting to identify those that are potentially threatening to Linux and open source. Then, the group looks for prior art that would invalidate at least some of the claims in the patents.'"

Good intentions but potentially harmful

Patent attorney here.

While it seems like this is a great idea, getting more prior art in front of the PTO is may not be the best strategy. It allows the patent applicant to try to amend the claims or argue around the prior art. A lot of the the time, the examiner responsible for a patent application is not particularly worried about the quality of the patent being issue but is more concerned with just getting the application off his/her docket. This makes it reasonably likely that the examiner will either ignore the new prior art or accept whatever dubious amendment/argument that the patent owner submitted. Once a patent is allowed over prior art that was made of record, it is much more difficult to use that prior art again later.

I would suggest that a better strategy is to just record and publish lists of prior art after the patent issues. Then, later on if the patent is asserted, there is easy access to fresh prior art that can be used to kill a patent.

Actually, I would say the opposite. Only a very, very small percentage of patents are ever actually asserted. Looking at every patent application that is published and submitting prior art with descriptions of the prior art is vastly more time consuming than simply looking up previously identified prior art and killing only those patents that are later asserted. Also, it is much harder to patent owners to amend claims after the patent has issued.
