ITC clears Microsoft phones of infringing on two InterDigital patents
U.S. International Trade Commission clears Microsoft of patent infringement — Microsoft Corp avoided a potentially costly setback to its mobile phone business on Friday as the U.S. International Trade Commission declined …
Context & Ripple Effects
This reversal closes a four-month arc: an ITC administrative judge found in April that Microsoft phones infringed two InterDigital patents, putting the company at risk of a costly import remedy on its mobile business. The full commission has now rejected that finding.
Timing matters — the decision lands eight days after Microsoft filed a federal antitrust suit accusing InterDigital of abusive licensing practices, and it follows a string of implementer wins against patent-holding firms, including the appeals court upholding Microsoft's $14.5M verdict against Motorola and Apple's clean verdict over Nokia-origin patents held by Core Wireless.
First-order effects
- Microsoft's phone business escapes the exclusion-order risk the April ruling created, removing immediate pressure to settle or raise royalty payments on the disputed patents.
Second-order effects
- InterDigital enters licensing negotiations from a weakened position — its core enforcement lever just failed at the commission level while facing Microsoft's antitrust challenge, which other licensees can now cite.
Third-order effects
- If the pattern holds — implementers beating licensors at the ITC and juries, as with Motorola and Core Wireless — standards-patent holders lose pricing power and may shift toward settlement-first licensing rather than litigation.
The trend: Handset makers are increasingly countering standards-patent licensors with antitrust claims and winning at the ITC and juries, eroding the leverage of licensing-driven patent firms.
