- • US 8,356,251 — Application No. 13/245,001; Claims 1 and 7 at issue. Covers methods and systems for controlling video playback across heterogeneous devices.
- • US 11,048,751 — Application No. 15/687,249; Claims 12 and 13 at issue. Covers methods and systems for controlling video playback across heterogeneous devices.

The Verdict & Legal Analysis
Outcome
The jury returned a unanimous verdict of non-infringement on all asserted claims across all three patents. The court entered judgment accordingly: Charter has not infringed any asserted claims of the ‘251, ‘751, and ‘934 Patents. Touchstream takes **nothing** against Charter.
Key Legal Issues
In streaming technology patent cases, non-infringement verdicts typically hinge on one of several grounds: claim construction divergence (where the jury or court construes claim terms narrowly, excluding the accused product’s architecture), **absence of a required claim element** in the accused system, or **credible non-infringement expert testimony** neutralizing plaintiff’s technical case. Charter’s multi-firm defense team was well-positioned to present granular system architecture evidence distinguishing the Spectrum TV App from the claimed inventions.
