Knobbe Martens Intellectual Property Law - Inter Partes Review
What is an Inter Partes Review? An Inter Partes Review (IPR) is a
counterpart to a Post-Grant Review (PGR) and provides another method
for challenging patents before the U.S. Patent and Trademark Office.
IPR and PGR share many of the same procedures and rules, but there are
several important differences between the two programs. What are the
major differences between an IPR and a PGR? While a PGR is available
for challenging patents only during the first nine months after
issuance, an IPR is available for challenging patents after this
initial window. While only patents filed after March 16, 2013 can be
challenged in a PGR, all patents regardless of filing date can be
challenged in an IPR. The grounds for challenging patents in an IPR
are more restricted than a PGR – an IPR challenger is limited to
arguing invalidity based on prior-art patents and printed
publications. What are the government fees associated with an IPR? The
government charges the following fees to institute an IPR: $9,000 -
IPR request fee (up to 20 claims); $14,000 - IPR post-institution fee
(up to 15 claims); $200/claim - IPR request fee for each claim over
20; and $400/claim - IPR post-institution fee for each claim over 15.
Is it better to challenge a patent in Federal court or with an IPR? An
IPR can offer advantages compared to challenging a patent in Federal
court. For example, an IPR can be relatively quick. Most proceedings
will conclude within about 18 months, compared to the several years
that many Federal court litigations require. An IPR can be less
expensive, particularly with respect to discovery costs. While some
discovery is allowed in an IPR, the scope is much narrower than
Federal court litigation. One potential disadvantage for patent
challengers who choose the IPR route is the estoppel effects. That is,
a patent challenger in an IPR may not assert in a later proceeding any
ground that it raised or could have raised in the IPR. What is
Knobbe Martens’ experience with IPRs? While IPRs were only recently
created, Knobbe Martens already has an active IPR practice. Knobbe
Martens is counsel of record in 18 pending IPRs, representing both
patent owners and patent challengers roughly equally. Our thorough
knowledge and experience in other PTO dispute proceedings, such as ex
parte reexaminations, inter partes reexaminations, and interferences,
combined with our proven record in Federal court patent litigation,
give us an advantage in the new IPR proceedings.
