UNITED STATES DISTRICT COURT

NORTHERN DISTRICT OF CALIFORNIA

SAN JOSE DIVISION

POWER INTEGRATIONS, INC.,

Plaintiff,

v.

ON SEMICONDUCTOR CORPORATION, 

et al.,

Defendants.

Case No. 16-cv-06371-BLF 

SUPPLEMENTAL ORDER 

CONSTRUING CLAIMS IN U.S. 

PATENT NOS. 6,297,623, 7,538,533, 

8,115,457

On October 26, 2018, this Court issued an order construing certain claims in several U.S. 

patents, including U.S. Patent Nos. 6,297,623, 7,538,533, and 8,115,457. See ECF 196. For each 

of these patents, the Court found a term indefinite in certain independent claims. The parties did 

not brief whether the asserted dependent claims associated with those indefinite independent 

claims were likewise invalid as indefinite. So, the Court instructed the parties to submit a joint 

statement advising the Court whether the parties agree that each dependent claim is indefinite 

because it is associated with an indefinite independent claim. See id. at 37–38. On November 9, 

2018, the parties filed a joint statement agreeing that “each asserted dependent claim of the ‘623 

patent, the ‘533 patent, and the ‘457 patent associated with an independent claim ruled upon by the 

Court is also indefinite by virtue of its incorporation of the terms of its associated independent 

claim.” See ECF 197. As such, the Court holds that any asserted claims dependent on an 

indefinite independent claim are likewise indefinite.

IT IS SO ORDERED.

Dated: November 13, 2018
