The Challenge

Two complex European patents in speech encoding

A multinational consumer electronics and telecommunications company headquartered in Japan engaged us to support prior art efforts on two complex European patents. The technologies involved advanced speech encoding and signal processing methods, calling for both subject-matter expertise and a structured approach.

Rather than a large volume of references, the client wanted a concise set of the most relevant prior art, along with clear technical support to help with review.

The Solution

Coordinated, efficiency-focused prior art search across two patents

To meet that objective, we coordinated multiple external researchers and directed the group toward high-value disclosures. Our work was designed around delivering a focused, reviewable set of materials rather than an exhaustive list.

Our approach included:

Focused researcher coordination

Directed a distributed group of researchers toward high-value, relevant disclosures.

Curated top references

Filtered results to isolate the most compelling prior art, delivering 2 to 3 top references per patent.

Claim charts and mixed-source coverage

Prepared technical claim charts mapping each reference to the patent claims, drawing on both patent literature and selected non-patent sources, including technical journal articles.

Our impact

A review-ready prior art set for both patents

We identified prior art for both patents while keeping the multi-researcher collaboration organized. The deliverables supported quick review and straightforward comparison against the claims.

Prior art identified for both patents

We identified relevant references for both patents while keeping cross-researcher collaboration organized and efficient.

Deliverables built for quick review

Claim charts and curated references supported straightforward comparison against the patent claims.

Well-rounded, client-approved work product

The client was satisfied with the quality of the references and the usability of the final work product, with the combination of patent and non-patent sources producing a well-rounded prior art set.
