SAN DIEGO, CA, Aug 11, 2015 (Marketwired via COMTEX) -- Memjet today filed a patent infringement lawsuit against Hewlett-Packard Company in the United States District Court for the Southern District of California. The lawsuit alleges infringement of eight Memjet patents related to its page-wide "waterfall" printing technology.
Specifically, the complaint asserts infringement of the following patents:
-- U.S. Patent No. 6,575,549, titled "Ink Jet Fault Tolerance Using
Adjacent Nozzles"
-- U.S. Patent No. 6,880,914, titled "Inkjet Pagewidth Printer For High
Volume Pagewidth Printing"
-- U.S. Patent No. 7,156,492, titled "Modular Printhead Assembly With A
Carrier Of A Metal Alloy"
-- U.S. Patent No. 7,325,986, titled "Printhead Assembly with Stacked Ink
Distribution Sheets"
-- U.S. Patent No. 8,662,636, titled "Inkjet Printhead Having Rows Of
Printhead Segments"
-- U.S. Patent No. 8,678,550, titled "Printhead Assembly With Laminated
Ink Distribution Stack"
-- U.S. Patent No. 8,696,096, titled "Laminated Ink Supply Structure
Mounted In Ink Distribution Arrangement Of An Inkjet Printer"
-- U.S. Patent No. 9,056,475, titled "Inkjet Printer With Web Feed
Maintenance Assembly"
The lawsuit seeks both to enjoin Hewlett-Packard from its unauthorized use of Memjet's patented page-wide waterfall technology, and to recover damages resulting from Hewlett-Packard's use of that patented technology in HP's PageWide printer products, including the Pro X generation of office printers, the T-Series commercial presses, and PageWide XL series products. HP has stated its intention to use its PageWide Technology across its printing portfolio including in future Wide Format and 3D printers.
Memjet has invested substantial resources in the research and development of its page-wide waterfall technology over the last decade. Memjet has protected that investment through the development of its significant patent portfolio, including several thousand U.S. and foreign patents in the page-wide inkjet printing space.
