Background
Google Technology Holdings LLC filed a patent application covering a method and apparatus for transferring video content in distributed caching systems for video-on-demand services. The patent examiner rejected the claims as obvious over prior art combinations, and the Patent Trial and Appeal Board affirmed the rejection. Google appealed to the Federal Circuit.
On appeal, Google argued for the first time that the claim terms “cost” and “network penalty” should be construed in a specific way that would distinguish the invention from the cited prior art. The problem was that Google had never advanced these specific claim construction arguments before either the examiner or the PTAB. The government argued that Google’s new arguments should not be considered because they had not been preserved in the administrative proceedings below.
The case presented the Federal Circuit with an opportunity to clarify the difference between two closely related procedural doctrines: waiver and forfeiture, and to explain their different consequences for issues raised on appeal for the first time.
The Court’s Holding
The Federal Circuit affirmed the PTAB’s rejection and held that Google had forfeited (not waived) its new claim construction arguments by failing to raise them during examination or on appeal to the Board. The court took the occasion to carefully distinguish these two related doctrines: forfeiture is the failure to make a timely assertion of a right; waiver is the intentional relinquishment or abandonment of a known right. The two have different implications.
When an issue has been forfeited rather than waived, the Federal Circuit retains discretion to consider it in exceptional circumstances — but ordinary cases where an applicant simply neglects to raise an argument before the USPTO will not justify that exercise of discretion. Here, Google had not made these claim construction arguments at any point before the examiner or the PTAB, and there was no exceptional circumstance that would justify taking them up for the first time at the appellate stage. The court affirmed the obviousness rejection on the prior art record as developed below.
Key Takeaways
- Claim construction arguments that are not raised before the patent examiner or the PTAB will generally be forfeited and cannot be raised for the first time on appeal to the Federal Circuit.
- Forfeiture and waiver are distinct concepts: waiver is an intentional abandonment of a known right, while forfeiture is simply a failure to timely assert a right. Only in exceptional circumstances will the Federal Circuit consider forfeited arguments.
- Patent applicants and their counsel must be careful to fully develop and present their claim construction positions during examination and any PTAB appeal, since the record created in prosecution is the record the Federal Circuit will use to evaluate the rejection.
- For patent prosecutors, this decision is a reminder that strategic claim construction arguments must be front-loaded in prosecution, not saved for appellate briefing.
Why It Matters
In re Google Technology Holdings provides a clear and practically important statement of the argument-preservation rules that govern patent prosecution appeals. Many patent applicants approach a Federal Circuit appeal as an opportunity to reframe the case with new arguments or fresh perspectives on claim construction. This decision underscores that such arguments are foreclosed unless they were properly presented below.
The case also helps clarify some terminology confusion in patent law. The terms “waiver” and “forfeiture” are sometimes used interchangeably, but the Federal Circuit made clear they are legally distinct. The practical consequence of this distinction is significant: forfeiture of an argument in prosecution is not an absolute bar (the court retains discretion), while true waiver — such as an express concession before the Board — may create a more severe preclusion. Practitioners should be aware of both doctrines when managing prosecution strategy and planning appeals.
