Deadlines that start on notice
Once a petition is instituted, the Board sets a deadline to answer, and a registrant who does not respond risks default judgment and loss of the registration. USPTO-initiated expungement and reexamination proceedings also set a response period, and the registrant generally has to submit evidence of use rather than simply object. Many owners learn of these proceedings late because the correspondence address on file is out of date, so it is worth checking that address now if you hold registrations. If a notice arrives, calendar the deadline before doing anything else.
Evidence of use and of priority
Most challenges rest on non-use of the mark or on a claim that the challenger used a similar mark first. Answering them usually depends on dated proof: product photographs, invoices, web pages captured with dates, advertising records, and sales figures covering the goods listed in the registration. Use on some goods does not save the registration for goods on which the mark was never used, so the listing may need to be narrowed. If use stopped for a while, the reasons and any plans to resume matter, and those facts should be gathered with counsel before any statement is made. Fraud claims, alleging knowingly false statements to the USPTO, are raised at times and are hard to prove, but they still deserve a careful answer.
Choosing how to respond
Responses include defending fully, narrowing the goods, negotiating a coexistence or consent arrangement, or surrendering part of the registration to focus on what matters. A cancellation decided against you changes the register but does not by itself award damages, though the same facts sometimes surface in a related infringement case. Board proceedings involve discovery and a trial on a written record, and costs can grow if the parties dig in. In a first conversation we review the petition or notice, your evidence of use, and any parallel dispute, and decide whether the registration is worth defending as filed.
