Patent suits target Google, Intel, hundreds more for encrypting web traffic

11 02 2013
An unknown company’s four-year campaign to sue hundreds of companies for offering encryption on their websites shows no signs of abating, with Intel, Yelp, and being targeted in the past month, court records show.

The patent infringement complaints, which have also named Google, Apple, eBay, and Expedia, claim that Marshall, Texas-based TQP Development is entitled to royalties for the companies’ use of the secure sockets layer and transport layer security protocols. Together, SSL and TLS form the basis for virtually all encryption used to authenticate websites and to encrypt data traveling between them and end users. The lawsuits assert US Patent No. 5,412,730, which is titled “Encrypted data transmission system employing means for randomly altering the encryption keys.”
