Honeyman Cipher "encryption" patent challenged as likely invalid

On December 13, 2019, Unified filed a petition for inter partes review (IPR) against U.S. Patent 5,991,399, owned and asserted by Honeyman Cipher Solutions, LLC, a Brad Liddle entity and well-known NPE.  The ‘399 patent, directed to secure distribution of information using encryption, has been recently asserted against Snap, Groupon, and LogMeIn for uploading mobile apps for authentication and distribution.

The patent was previously asserted in 2015 and 2016 by Plano Encryption Technologies (another NPE) against banks and various other companies (State Farm, Best Buy, Etsy, Match.com, Shutterfly) before being transferred to Honeyman for the most recent campaign.
