Case Summary:
Wilmington-based, non-practicing
entity, Micro Design filed a complaint against computer technology companies
including: Lenovo, Fujitsu, Dell, NEC and ASUSTeK. The suit concerned the
companies’ infringement of a U.S. patent covering communications among
processors, coprocessors and memory. The cases were filed on Jun 27, 2014 in Delaware
District Court.
Patent-in-Suit:
The patent at issue is: US7437535
‘Method and apparatus for issuing a command to store an instruction and load
resultant data in a microcontroller,’ duly issued by USPTO on Oct 14, 2008 and expiring[i]
by Apr 04, 2022. The patent has been through multiple assignees including: Net Navigation
Systems and Clearwater Innovations. Micro Design is the current assignee[ii]
of the patent (source: MaxVal’s Assignment
Database.) The ‘535 patent describes a method of providing single-cycle
instruction (store-and-load) that stores a command to a co-processor to automatically
process data and that loads resultant processed data.
As in Complaint:
Lenovo infringed the patent by designing
microprocessors that contain the claimed combinations of the patented
technology, including the processor, co-processor and memory accessing features.
The accused products include: ThinkStation C30, D30 and S30. The complaint
stated that Lenovo’s actions aid and abet others (such as their partners and
customers) to infringe using the accused products by advertising and
distributing the accused products.
The complaints filed against
other defendants were substantially similar.
Micro Design sought damages from all the defendants and demanded a jury
trial.
