PPC Study Guide 2026

The International Search Report (ISR) is a list of prior art documents considered relevant to the PCT application's claims, prepared by an International Searching Authority (ISA) such as the USPTO, EPO, or JPO.

Data security is fundamental in PPC practice, protecting sensitive professional and client information from unauthorized access, breaches, and loss.

After the EPO grants a European patent, the patentee must validate it in each desired EPC member state by paying national fees and, in many countries, filing an official translation within a set deadline (typically 3 months from grant).

Integrating compliance into standard operating procedures makes it part of routine practice rather than a separate, burdensome activity.

In the United States, a utility patent typically lasts for 20 years from its earliest effective filing date. This period grants the inventor exclusive rights to their invention, preventing others from exploiting it without permission. To maintain the patent's validity throughout this term, periodic maintenance fees must be paid to the USPTO.

PCT Chapter II offers an optional International Preliminary Examination (IPEA) that provides a deeper patentability assessment through demand filing, giving applicants more information before entering the national phase.
