After Searching: Patent Filing Options and PCT ISAs

According to WIPO data, USPTO, EPO and KIPO are major ISAs for U.S. applicants; about 94% of intentional searches have been done by these three patent offices. U.S. applicants may consider the quality of search reports and cost of search fees as the most important factors in selecting an ISA. Search fees vary by ISA, for example, EPO’s rate is relatively high $2,125, USPTO’s rate is $2,080, and KIPO is well known to provide high quality earches with a relevantly competitive cost at $1,219.
