HD Silicon Solutions LLC v. Microchip Technology Inc.

Background

HD Silicon Solutions LLC sued Microchip Technology Inc., alleging infringement of seven patents through several accused products, including PIC24, PIC32, PolarFire, and SAM L11 products. Microchip moved under 28 U.S.C. § 1404(a), a statute allowing a federal court to transfer a civil case for the convenience of the parties and witnesses, to transfer the case from the Western District of Texas to the Northern District of California.

The opinion states that HD Silicon Solutions is a Texas limited liability company with its principal place of business in the Southern District of California. It states that Microchip is a Delaware corporation headquartered in Chandler, Arizona, with a significant presence in the Northern District of California.

Transfer Standard

The court first determined whether the case could have been brought in the Northern District of California. Neither party disputed that venue there was proper, and the court found that the case could have been filed there. The court then considered private and public interest factors and required Microchip to show that the proposed destination was clearly more convenient than the Western District of Texas.

Private-Interest Factors

The court found that access to sources of proof weighed only slightly in favor of transfer. Although some relevant evidence was in the Northern District of California, the great majority of relevant technical, marketing, and financial documents appeared to be in Chandler, Arizona, outside both districts. The court also noted that the parties identified no relevant evidence located in the Western District of Texas.

The availability of court orders compelling witnesses to attend favored transfer. Microchip identified inventors of the asserted patents and prior-art inventors in the Northern District of California who, according to Microchip, had not agreed to provide information. The court gave little weight to Microchip employees and distributors in Texas because the employees appeared to have only a remote relationship to the case and sales information from distributors would likely be available from Microchip during evidence gathering.

The cost and convenience of attending court for willing witnesses weighed strongly in favor of transfer. The court found that most party witnesses and potentially willing third-party witnesses lived in the Northern District of California, while there were no relevant witnesses in the Western District of Texas. The parties agreed, and the court found, that other practical problems affecting trial were neutral.

Public-Interest Factors

Court congestion weighed against transfer because the Western District of Texas had a faster average time to trial, although the court said this factor had little effect on the overall result.

The local-interest factor favored transfer. The court focused on where the design, development, and sale of the accused products occurred. It found that few, if any, events supporting the infringement claims occurred in the Western District of Texas and that the Northern District of California had relevant engineers and development activity for some of the accused products.

The parties agreed that the courts’ familiarity with the governing law and problems involving conflicts of law were neutral, and the court agreed.

Disposition

The court summarized the factors as follows: four favored transfer, ranging from slightly to strongly; one weighed against transfer; and three were neutral. It concluded that Microchip had shown that the Northern District of California was clearly more convenient than the Western District of Texas.

The court therefore granted Microchip’s motion to transfer. It ordered the clerk to transfer the case to the United States District Court for the Northern District of California for all further proceedings and, after transfer, to close the Western Texas case.

Judge

Judge Alan D. Albright signed the order on October 25, 2021.
