Juristat Top Patent Firms | Semiconductors

Semiconductor dockets range from device physics to EUV lithography to RF front-ends—each with distinct examiner mixes and claim strategies. Ranking by allowance rate within H01L/H01J/H01Q isolates performance in the work you actually prosecute. It levels the field across firm size and mix and centers the outcome clients care about: Did the work convert to granted rights in this industry? CPC granularity keeps comparisons apples-to-apples, so a device-structure specialist isn’t measured against a lithography-heavy docket, and vice versa.

The result: fair, comparable standings you can defend in a partner meeting or an RFP.

How we define the Semiconductor industry

Semiconductors span device structures, fabrication processes, lithography, packaging, and RF front-ends—often overlapping with electronics manufacturing and wireless. To keep comparisons fair and apples-to-apples, we anchor this view to CPC subclasses that most directly capture semiconductor devices and the processes that make them. We emphasize H01L (semiconductor devices/processes), H01J (ionizing radiation for fabrication, e.g., certain lithography), and H01Q (antennas where chip-integrated or RF front-end is central to the invention).
