Chief Judge Gregory M. Sleet: Markman Opinion

By Karen E. Keller, Andrew A. Lundgren et al.

In a case involving a patent covering high performance diodes (electronic components), Chief Judge Sleet construed the following terms:

- "semiconductor substrate of a first conductivity type"
- "pedestal"
- "on [the first substrate of] the substrate"
- "side regions"
- "channel region in the substrate below the first oxide layer under the side regions"
- "a buried layer of a second conductivity type under and between the side regions"
- "the substrate between the side regions"

Of note was the Court's comment that it "adopted the defendant's proposed construction of [the term "semiconductor substrate of a first conductivity type"]...as a sanction for the plaintiff's failure to follow its Markman procedures." Id. at 1, n.1.
