Background
In the Matter of Semiconductor Chips with Minimized Chip Package Size and Products Containing Same (III)
Investigation: 337-TA-630
Representation: Respondents
Claims: Patent Infringement
Technology: Packaging of DRAM Chips
Scope of Involvement: Report, Deposition, Hearing Testimony
Engagement
Tessera brought suit against several respondents who were accused of importing infringing DRAM chips. Ocean Tomo offered testimony that the majority of units sold in or imported into the U.S. by respondents were purchased from suppliers or subcontractors directly licensed by Tessera, and thus licensed.
Results
The Administrative Law Judge, in agreement with Ocean Tomo, found that all chips purchased by Defendants from Tessera’s licensees were authorized. Thus, because Tessera’s rights in those chips were exhausted, none of Tessera’s patents had been infringed. Consistent with those findings, the Commission’s final determination found that there was no violation of Section 337.
