Proppant Express Investments Prevails in Patent Trial and Appeal Board Ruling Resulting in Invalidation of SandBox Logistics ...
September 16 2019 - 7:25AM
Proppant Express Investments, LLC (PropX) today announced that the
United States Patent and Trademark Office (USPTO) through the
Patent Trial and Appeal Board (PTAB) invalidated patent claims of a
SandBox Logistics, LLC (“SandBox”) patent. Specifically, the
PTAB found that all 18 claims of Sandbox’s U.S. Patent 9,440,785
(the “785 Patent”) challenged by PropX are unpatentable in an inter
partes review (IPR) proceeding. SandBox is a subsidiary of
U.S. Silica Holdings, Inc. (NYSE:SLCA).
With this ruling, the PTAB has issued rulings on
all the asserted patents currently challenged by PropX through IPR
proceedings and, in each case, has invalidated the majority of
claims from the SandBox patents. The PTAB has invalidated 53 patent
claims (out of a total of 60 challenged) which were contained in
four patents challenged by PropX.
“This ruling strongly supports PropX’s position
as the leading provider of last mile sand logistics solutions to
the oilfield services industry and reinforces PropX’s legal
position in their unique, differentiated technology,” said Kevin
Fisher, President and Chief Executive Officer of PropX. “We are
pleased PropX prevailed in both our non-infringement defense and in
our patent invalidity arguments. Combined with our victory in
federal court in January of this year that we do not infringe on
SandBox patents and additional PTAB rulings invalidating other
Sandbox patent claims, this PTAB ruling should eliminate any doubt
that PropX has unique technology that fairly and strongly competes
in the sand logistics industry. We look forward to continuing to
grow our position as the premier last mile delivery provider and
remain committed to serving our customers with our unique,
efficient and market-leading containerized sand logistics
systems.”
