A Better Way to File Patent Applications

The PathWays system is designed to help applicants predict which art units an application is likely to be filed before the application is even filed. A unique semantic search algorithm compares user submitted text to weighted key words derived from an exhaustive collection of application documents clustered in each USPTO art unit.

An Exclusive Interview with USPTO Director Michelle Lee

There were no topics ruled out of bounds for this 30 minute interview, not even the Supreme Court’s recent decision to accept cert. in Cuozzo, although as an attorney myself I know better than to ask questions that would have certainly provoked a polite “no comment” response in the face of ongoing litigation. Nevertheless, our conversation was wide ranging. We discussed the release of the Copyright White paper, which among other things recommends expanding eligibility for statutory damages in copyright infringement actions. We also discussed Lee’s recent visit to the Consumer Electronics Show (CES), the power outage that brought down USPTO electronic filing systems, the Office’s patent quality initiative, the new patent classification system, the Patent Trial and Appeal Board (PTAB) and more.

Patent Searching 101: A Patent Search Tutorial

Inventors and entrepreneurs who are looking to cut costs frequently want to do their own patent search. This is a wise first move, but inventors need to be careful. It is quite common for inventors to do a patent search and find nothing even when there are things that could and would be found by a professional searcher. So while it makes sense to do your own search first, be careful relying on your own search to justify spending the thousands of dollars you will need to spend to ultimately obtain a patent. In other words, nothing in this article should be interpreted as me suggesting that inventors can or should forgo a professional patent search. There is simply no comparison between a patent search done by an inventor and a patent search done by a professional searcher. Having said that, every inventor should spend time searching and looking if for no other reason than to familiarize themselves with the prior art. Of course, if you can find something that is too close on your own you save time and money and you can move on to whatever invention/project is next.

When USPTO Classifies an Application Incorrectly

This case had been made Special on the Patent Prosecution Highway in October of 2013 because of a favorable Written Opinion from a PCT Searching Authority. For a Special case, USPTO’s case management system normally starts ringing an alarm on the Examiner’s desk after a couple of months. So we should have seen an Office Action at least a month ago, maybe two months ago. But that only works if the case has been assigned to an Examiner. Often the USPTO first assigns the case to a SPE and then it is left to the SPE to figure out which Examiner in the SPE’s art unit should actually examine the case. This case got assigned to the SPE in a particular art unit. Let’s call him “SPE V”. It seems that SPE V decided that this case had been misclassified and should not have gone to his art unit. So he tried to get rid of it.

Using US Patent Classifications to Enhance Key Word Searching to Achieve Higher Quality Patent Search Results

I have found it helpful to think about patent classifications as being large buckets with subclassifications being little buckets within the larger classification buckets. There are currently more than 450 classifications and over 150,000 subclasses. According to the USPTO, “A class generally delineates one technology from another. A Subclass delineates processes, structural features, and functional features of subject matter encompassed with the scope of the class.” It is also important to realize that although every patent has only one primary classification (class and subclass) it may include others as applicable to the patent.
