The Challenge

NPE litigation against a biometric security innovator

A U.S.-based provider of biometric identification and security solutions was sued by a non-practicing entity (NPE) asserting three patents related to biometric technologies. The company develops advanced fingerprint identification, facial recognition, and iris scanning technologies. The three asserted patents were not new to litigation as they had been asserted in nearly 40 infringement cases against some of the world’s largest technology companies, including Apple, Google, Microsoft, Panasonic, Kyocera, and Fujitsu.

With a plaintiff known for aggressive patent enforcement, outside counsel needed comprehensive prior art capable of challenging the validity of the asserted claims.

The Solution

Global prior art strategy across three asserted patents

To support their case, outside counsel engaged our team to conduct comprehensive prior art searches across all three asserted patents. The objective was clear: uncover strong prior art that could challenge the validity of the patents. We executed a multi-faceted, global search strategy tailored to provide a diverse pool of prior art documents, working closely with counsel to ensure the results were both technically rigorous and strategically aligned with the litigation defense.

Our approach included:

Comprehensive global search

Reviewed 209 prior art references across multiple sources, including U.S. patents, Japanese patent publications, and international filings.

Non-patent literature analysis

Examined technical documentation and user manuals to broaden the evidentiary base beyond patent literature.

High impact prior art selection

Prioritized disclosures capable of invalidating key claim elements to directly support the litigation defense.

Our impact

Strengthened invalidity contentions

Our efforts provided the litigation counsel with comprehensive prior art that informed their defense strategy and ultimately contributed to a favorable outcome.

Case dismissed with prejudice

The client fully defended against all allegations, closing the matter without further exposure.

Zero settlement, zero damages

The company avoided any financial payout despite facing patents with a history of nearly 40 infringement suits.

Defense strengthened against NPE assertion

Prior art insights directly countered a plaintiff with a track record of asserting claims against major technology companies.

Need better results before litigation costs escalate?

For companies facing repeated assertions from non-practicing entities, the ability to uncover and leverage strong prior art can be the difference between costly settlements and winning.
