A U.S. patent infringement lawsuit was filed on June 10, 2009, against Hamamatsu
Photonics K.K., Hamamatsu
Corporation, and Olympus America, Inc. The lawsuit, brought by Aperio Technologies,
Inc. in the U.S. District Court for the District of Delaware, accuses products
incorporating Hamamatsu Photonics K.K. NanoZoomer(R) technology of infringing
Aperio U.S. Patent Nos. 6,917,696; 7,457,446; and 7,518,652.
The lawsuit follows a series of letters issued by Aperio in which Aperio alleged
infringement. Hamamatsu Photonics K.K. has carefully analyzed the asserted claims
and concluded that its NanoZoomer(R) product is not covered by any of the patents
that Aperio has identified. Hamamatsu Photonics K.K. responded to each letter
from Aperio by pointing out its belief that the asserted patents did not cover
the Hamamatsu Photonics K.K. NanoZoomer(R) technology. Aperio has not responded
to any of the requests by Hamamatsu Photonics K.K. for further details and information.
Instead, Aperio filed the current lawsuit in U.S. District Court, without any
reply to the non-infringement positions brought to its attention by Hamamatsu
Photonics K.K.
Hamamatsu Photonics K.K. respects the valid intellectual property rights of
other companies, and has an excellent reputation world-wide for dealing fairly
with its competition. Hamamatsu Photonics K.K. believes that its NanoZoomer(R)
technology is not covered by any valid claims of the patents asserted by Aperio
in the pending litigation. Hamamatsu Photonics K.K. will vigorously defend itself
and fully expects to achieve a favorable outcome before the U.S. District Court
for the District of Delaware.
