This examiner grants 44% of resolved cases

Analysis

PILLAY, DEVINA is assigned to technology center 1700 and art unit 1725. The profile records 804 resolved cases and an allowance rate of 44.4%. The substantial volume supports a clear view of the outcome pattern, which shows that allowance is not the predominant result.

The median time to allowance is 1258 days. Interview lift is 25.5%, indicating that interviews are associated with a higher allowance rate than matters without interviews. That positive relationship provides a practical reason to prepare interviews carefully in difficult cases.

The recurring companies are LG Energy Solution Ltd., Panasonic Holdings Corporation, and Contemporary Amperex Technology Co., Limited. The listed firms are BIRCH STEWART KOLASCH & BIRCH, LLP, HAUPTMAN HAM, LLP, and MICHAEL BEST & FRIEDRICH LLP (Mke). Counsel should anticipate extended prosecution and use both claim refinement and interviews to address the relatively challenging allowance environment.
