Impact Stories

Finding a killer art is an ‘art’

A Fortune 100 company in the printing industry with a very strong R&D infrastructure requested 15+ Silver Bullet Invalidity searches in a quarter.

Supporting Licensing program through validity searches

A leading Japanese IP asset managing (licensing) company consults Sagacious IP for evaluating the validity of IP assets before launching any commercialization program.

Portfolio Building support through syndicated validity searches

A Swiss-based global market leader in development, production & marketing of actuator solutions is supported by Sagacious IP with quick validity checks and patent strength analysis for acquisition.

Native Language Search played the trick!

A US-based law firm requested Sagacious IP to perform Native Language search for a memory related patent portfolio. The strategy of collaborative searching became highly successful as it captured many non-English references that could not be identified through machine translation.

Patience in the key to invalidate an SEP

Our contextual analysis capabilities related to both patents and NPL, coupled with the ability to understand standard databases, played a crucial role in invalidating telecom related SEPs. Continuous interactions/calls with the attorney and multi-fold search iterations were instrumental in building the flawless argument against these SEPs.

Sagacious as an extension to Customer In-house IP Team

One of the biggest Fortune 100 US cloud computing companies trusts Sagacious IP for all their silver bullet invalidity searches to knock down the patents filed in infringement lawsuits against their product line.

NPL Searching is more important than patent search in some cases

In response to validity search request by one of our European law firm clients for a patent with a huge list of backward citations, Sagacious IP adapted a non-conventional approach. Depending on the technology area, we relied more on organic image analysis and scanned through tutorials/review videos to identify concrete evidence in a user-posted video on YouTube.
