Biddle joined Microsoft in 1990. Biddle was one of the first authors to describe the concept of darknet, a founder of the Secure Digital Music Initiative (SDMI), Copy Protection Technical Working Group, and Trusted Computing Platform Alliance, an early technical evangelist for DVD and digital video recorder technology, the founding leader of Microsoft’s Next-Generation Secure Computing Base (code named Palladium) initiative, and was responsible for starting Microsoft's Hypervisor development efforts. He built and led the engineering team that shipped BitLocker Drive Encryption, a Trusted Platform Module-rooted disk encryption for Windows Vista.
In 1998, Biddle publicly demonstrated real-time consumer digital video recorder functionality using an inexpensive MPEG2 hardware encoder, at the WinHEC conference during a speech by Bill Gates. Biddle was the author of the diagram on page 13 in the SDMI specification, which enabled the playback of “unknown” (potentially pirated) content on SDMI-compliant players, and was a vocal proponent within SDMI for the external validation of digital watermarking.
Biddle joined Intel Corporation in 2008 as a director of the Google program office. In 2009 he was a witness in the RealNetworks, Inc. v. DVD Copy Control Association, Inc. case. In 2011 he hosted an Internet program called "Mashup Radio".
