Yangtze Memory Technologies Co., Ltd.

Technology areas: Computing & Software • Semiconductors, Circuits & Optics

Analysis

Yangtze Memory Technologies Co., Ltd. operates in Semiconductors, Circuits & Optics with 148 pending office actions. These actions are spread across 121 distinct examiners, which indicates a high degree of variety in the individuals reviewing their semiconductor innovations. The portfolio is active in 32 distinct art units, showing a wide reach across different technical sub-specialties. This distribution across 32 art units suggests that the company's patent strategy must be robust enough to withstand scrutiny from many different technical perspectives.

AHMED, ZUBAIR is the busiest examiner for the company, currently overseeing 4 of the 148 pending office actions. Despite the high total of 148 actions, the involvement of 121 distinct examiners means the company is not overly reliant on any single examiner's discretion. The presence of 32 distinct art units suggests that the company must navigate a complex array of examination standards. This decentralized approach to prosecution can lead to a more resilient portfolio, as outcomes are not tied to the specific preferences of a small group of examiners. Practitioners should be prepared for a wide range of examiner behaviors across this diverse set of art units.

Case Difficulty Mix

Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
