RESTORATION & RE-ESTABLISHMENT
Restoring valuable patent rights
At PURDYLUCEY, we help clients recover patent rights that have been lost following missed deadlines, guiding them through complex restoration and re-establishment procedures across multiple jurisdictions.
Restoration proceedings are time-critical, jurisdiction-specific and often complex. The right specialist can make all the difference.

Missing a patent deadline does not always mean that patent rights are lost permanently. Depending on the jurisdiction and the circumstances, it may be possible to revive a patent application or patent through established legal procedures. These processes are often complex, time-sensitive and subject to strict legal tests, making experienced representation essential.

PURDYLUCEY has extensive experience in such proceedings in Ireland, the UK, and before the European Patent Office (EPO). Re-establishment of patent rights before the EPO is particularly demanding due to the strict legal standards that apply. Our team has successfully handled a number of complex re-establishment cases before the EPO, helping clients recover valuable patent rights in challenging circumstances.

As UK-qualified patent attorneys, we are able to act directly before the UK Intellectual Property Office (a capability that many Irish firms do not offer).

We also regularly work with trusted foreign associates to coordinate proceedings in jurisdictions including France, Spain, Germany, Switzerland and Norway, to name a few, providing clients with seamless support across international patent portfolios.

We can assist with
  • Patent restoration proceedings in Ireland and the UK after a missed renewal fee deadline.
  • Re-establishment of rights before the European Patent Office (EPO) after a missed deadline or a renewal fee.
  • Re-establishment of rights relating to Unitary Patents.
  • International restoration strategies across multiple jurisdictions.
  • Coordination of restoration proceedings through our trusted international associate network.


Whether your case involves a single missed deadline or a complex international portfolio, our team can advise on the available options and guide you through the process smoothly and effectively.
