Semiconductors & Electronics

Claims written by people who have read a process flow.

Semiconductor patents fail in predictable ways: a claim tied to a process node that moves, a structural limitation that a competitor's integration scheme sidesteps, a specification that never enabled the corner case. Avoiding those requires drafting from an understanding of how the device is actually built.

We prosecute and litigate across the semiconductor stack — device physics and structures, analog and mixed-signal circuits, memory, power electronics, packaging and interconnect, fabrication process and equipment, and the metrology around them. The same coverage extends to consumer electronics, displays, imaging and optoelectronics, and RF and antenna systems.

That coverage shows in the portfolios we manage: system-on-chip architectures, memory cell structures, photolithography and deposition processes, and the analog circuitry that surrounds them.

Claims that outlive the process node

A structural limitation calibrated to one node becomes a design-around instruction two nodes later. Semiconductor claims hold their value when they recite the functional relationship that makes the structure work — the doping relationship, the interface behavior, the thermal path — rather than the dimension that happened to be current when the application was filed.

Getting there requires reading the process flow, not the invention disclosure summary. It is why the drafting is done by people with the underlying training.

Where infringement is actually detectable

A claim covering an internal process step is a claim nobody can prove is infringed without a fab tour. Claims that read on the finished device — something visible in cross-section, in a die photograph, or in electrical characterization — are the ones that can be asserted. A portfolio needs both, and needs to know which is which before it needs to enforce anything.
