Endeca: Facets of Novelty

August 1, 2015

I am no specialist in the arcane art of legal eagle spotting. I did notice some references to a dust up between an outfit called Speedtrack and licensees of Endeca’s ageing search technology.

The Speedtrack outfit seems to have rights to an invention called “Method for Accessing Computer Files and Data, Using Linked Categories Assigned to Each Data File Record on Entry of the Data File Record.” This is explained brilliantly in US5544360, filed in February 1995.

Here’s a diagram showing how the user can click on categories to locate information. No typing required.

Compare this to Endeca’s invention, “Hierarchical Data Driven Navigation System and Method for Information Retrieval.” This is US7062483, filed in 2001. You may also find US7035864 and US7325201 interesting as well.

Federal Circuit Reaffirms Kessler Doctrine As A Patent Infringement Defense For Customers” explains that the Speedtrack infringement case pivots on the Kessler doctrine. Here’s the explanation from the JDSupra.com article:

First, unlike res judicata, which is a defense that is personal to the parties in a prior litigation, the Kessler Doctrine “attaches to the [accused] product itself” and precludes a patentee from reasserting the same patent against the same (or “essentially the same”) product in a subsequent action.

Then noted:

Second, the Federal Circuit ruled that the Kessler doctrine may be raised by customers as well as the product manufacturer or supplier.

What I found fascinating was this infringement related statement attributed to the presiding legal eagle:

Third, the Federal Circuit held that the Kessler doctrine applied to Speedtrack’s claim even though the Endeca software allegedly infringed only when combined with the customer’s own computer hardware.

I recall that Endeca’s faceted navigation burst upon the scene in the late 1990s. Who knew that Jerzy Lewak (co founder of Speedtrack), Slawek Grzechnik, and Jon Matousek seemed to be trying to figure out a way around the problem of keyword search before Endeca?

I wonder if Oracle were surprised too. I have a hunch Speedtrack was.
