Introduction<\/h2>

A semiconductor product designed by a Taiwan fabless company, fabricated at TSMC, using components from Korean and Japanese suppliers, targeting consumer electronics markets in Japan, Korea, the United States, and China. This is not a hypothetical supply chain. It describes a significant proportion of global semiconductor products shipped today.<\/p>

The IP clearance requirements for this product \u2014 before it ships \u2014 cover four of the world’s five largest patent offices: JPO (Japan, 307,000 applications per year), KIPO (Korea, 246,000 per year), TIPO (Taiwan, 70,000 per year), and CNIPA (China, 1.8 million per year). The relevant prior art exists in Japanese, Korean, Traditional Chinese, and Simplified Chinese. The blocking patents could have been filed by a Japanese conglomerate, a Korean semiconductor giant, a Chinese state-owned enterprise, or a US company that filed PCT and entered the national phase in all four jurisdictions.<\/p>

Most APAC IP teams handle this by running four separate searches, in four separate tools, and asking an analyst to merge the results. This is where clearance falls apart.<\/p>

The Four-Office Problem in Detail<\/h2>

Each of the four major APAC patent offices has different characteristics \u2014 different filing conventions, different language requirements, different technical domain concentrations \u2014 that affect how prior art search needs to be conducted. Running the same keyword search across four separate database interfaces does not account for these differences. It produces four result sets in four different formats that require an analyst to deduplicate, translate, and synthesise into a unified assessment.<\/p>

What Breaks at Each Seam<\/h2>

The JPO-KIPO seam<\/h3>

Japanese and Korean semiconductor companies file at both JPO and KIPO \u2014 often with the same underlying technology disclosed in Japanese at JPO and Korean at KIPO, with material differences in claim scope between the two jurisdictions. A search that covers JPO but not KIPO may find the patent family but miss the Korean claim variant that has broader scope. A search that covers KIPO but not JPO may miss the earlier filing that establishes priority. The relevant prior art picture for any technology with both Japanese and Korean competitive filers requires both jurisdictions \u2014 simultaneously, not sequentially.<\/p>

The TIPO-CNIPA seam<\/h3>

Taiwan and Chinese patent filings often cover the same technology \u2014 but TIPO filings are in Traditional Chinese, while CNIPA filings are in Simplified Chinese, and the technical terminology has evolved differently in the two patent systems. A keyword search optimised for TIPO terminology will not reliably find the CNIPA equivalent. A search optimised for CNIPA terminology may miss the TIPO filing that was the earliest disclosure. Semantic cross-language search that spans both systems is not a luxury \u2014 it is the only way to find the blocking reference that exists at one office but not the other.<\/p>

The language seam within CNIPA<\/h3>

CNIPA’s historical corpus \u2014 pre-2010 filings in sectors like telecommunications, industrial electronics, and manufacturing technology \u2014 has Chinese-language abstracts with limited or no English translation in most global databases. A global prior art search that does not specifically address this historical Chinese-language corpus is systematically missing the earlier Chinese prior art that may predate the international patent families that appear in English-language searches.<\/p>

The Internal Routing Challenge<\/h2>

The clearance problem is compounded by the organisational structure of most APAC-facing IP operations. An MNC with significant APAC exposure typically has:<\/p>
