Patent Research is Not Easy

Identifying the most pertinent patents in a list of thousands can be tedious and difficult. - IPWatchDog, Aug 2016

Why patent research matters?

Patents & Inventors

Patent Research• Information retrieval in patents• Beyond keyword search

Go Beyond Keywords

• Strategic Research tool

Improve Efficiencies

Patent Similarity

What if your keyword doesn’t get Patent 8 as a hit?

If Patent 4 & 5 are relevant, why not look at Patent 8?

Similarity Measures

Latent Dirichlet Allocation (LDA):

● “The basic idea is that documents are represented as random mixtures over latent topics, where each topic is characterized by a distribution over words.” (Blei, Ng, & Jordan)

TF-IDF:

tf-idft,d = tft,d x idft

• High when term occurs often in few documents

• Lowest when it occurs in all documents (think stop words)

Patent LinkWe wanted to allow the user to review the patents we recommend.

Clicking on the link was natural and required no explanation.

Page 24: Patent Recommendation System

Future Work● Future: User click on show more most of the time, start out with a larger list● “patent continuations” we want to incorporate a way to deal with these. Don’t

want to have continuations showing up in patent profiles or dominating the recommendations

● Future: Adding patents to profile from here. Would allow us to look at precision as an evaluation of the recommendations.

● Future: Click on score to see indication why (keywords, topic,..) to allow user to evaluate recommendation without reading. Allows to generate new keywords as well as filter out false positives.

The Big PictureWe see this page becoming a sub-page to a user profile. The profile could contain many collections, and when you login, you get to see prompts for looking at recommendations on established collections again. That was one of the comments we got, that he sees this as a stepping stone to that.
