Patent Opposition
One of the most challenging plays in major league baseball is a triple play – making three successful outs on one batted ball. Dennemeyer has developed its own version of the “triple play” for European oppositions and is able to assist and counsel throughout the entire three step opposition process.

The UK Intellectual Property Office (UKIPO) provides opinions on the validity of granted patents including European patents that are validated in the UK. Only newly raised grounds for invalidity will be analyzed, but insufficiency arguments and added matter arguments may be raised as well. We use these opinions to help you oppose a competitor’s European patent that stands in your way. We do this in three steps which, using the analogy of baseball, we call our “triple play”. Play 1: We analyze whether unallowable extension (added matter), insufficiency or new prior art could be argued. Play 2: If so, we file a request for an invalidity opinion with the UKIPO. Play 3: If the opinion of the UKIPO finds invalidity, we file an EP opposition for you.

Throw hard — hit fast

A UKIPO opinion can be requested as soon as the patent is granted and is usually delivered within 3 months, i.e. well before the 9 months’ deadline for an EP opposition.

Official opinion at low price

An official opinion from the UKIPO is a mighty advantage for your team. The official fee is only £200.

Wake up call for the umpire

Following a request for an opinion, the UKIPO might start an "ex officio invalidity proceeding" against the UK part of the EP patent.

Invisible play

The requester of a UK patent opinion need not act under his own name — the demand can be done by a straw man.
