IP Strategy · Patent Map
What is intellectual property strategy?
- A patent map shows where competitors are investing
- Decide your purpose first: defend, attack, or exploit
- Trademarks and contract rights ownership cause problems more often
What IP strategy changes is not the documents but the development sequence. A team that used to go straight into design as soon as an idea appeared now spends 2–3 weeks on prior-art checks before kickoff and sets the design direction based on the results. A patent map puts the evidence on a single page, so when R&D’s confidence collides with sales’ gut feel, meetings that the loudest voice used to win turn into evidence-based comparisons. What changes is not the conclusion itself but how you reach it.
In practice, patent searches fall into three types by purpose: a prior art search to gauge patentability before filing, a freedom-to-operate (FTO) search to check whether you would infringe others’ rights before launching a business, and an invalidity search to knock out a rival’s patent once a dispute starts. Lump them together as a “patent search” and you will get the wrong deliverable. Free search services can sketch a rough map in a week, but a formal patent map that examines the claims is an outsourced project that typically takes 2–3 months and costs tens of millions of won.
You also need to know the assumptions behind reading one. Applications are generally published 18 months after filing, so the map you see today is missing the last 18 months of competitor activity entirely. The scope of rights is set by claim 1, not by the description of the invention. The term runs 20 years from the filing date and ends earlier if annual fees go unpaid. Expired or lapsed patents are public technology anyone can use, so classify them as something to exploit, not design around.
The most common misconception is “We hold a patent, so we can sell.” A registration is only a right to exclude others; it does not guarantee your freedom to operate, so practicing an improvement patent built on another company’s basic patent is still infringement. Treating white space as automatic opportunity is also risky. Where no one has filed, there is often no market, or a technical barrier. On top of that, if you leave out the rights-ownership clause in the contract and the copyright in outsourced training materials or videos stays with the producer, you will pay new fees or have to start over when you publish a revised edition three years later.

Kwangdong MinExpert in business models, revenue models, and market researchUsing patent information for business strategy was systematized in Japanese and U.S. corporate IP management discussions from the 1990s onward. In Korea as well, the Korean Intellectual Property Office and related agencies have promoted patent trend analysis as a new business planning tool.
Consider a hypothetical case. Company A, an industrial sensor manufacturer with 160 employees and annual revenue of around KRW 42 (≈ US$1) billion, put thermal-imaging equipment diagnostics on its list of new business candidates. R&D said, "We can have a prototype in a year," but executives, worried by rumors that two large corporations had already entered the field, postponed approval twice without any evidence. Finally, the head of technology planning proposed running a 12-week patent map project before starting development.
- The technology planning team lead pulled 2,180 domestic and international filings from the past 10 years using three IPC codes and keyword combinations. Over two days, working with a patent attorney to strip out noise, they cut the analysis set to 947.
- When they charted filings by year, they had been falling every year since a peak in 2019. The head of the research institute said, "We thought it was a growth market, but it had already gone through its cycle and consolidated."
- Seven of the top 10 applicants were Japanese or German companies. Filings from two major Korean corporations clustered in cloud diagnostic software rather than equipment hardware, which showed that the competition was playing out on a different axis.
- They reviewed the 14 registered patents overlapping the business plan, claim by claim, starting with claim 1. The 3 key ones turned out to expire in 2027, and for 2 of them they received an opinion that a design-around is possible just by changing the sensor placement.
- Executives approved the project after narrowing its scope from finished equipment to sensor modules and diagnostic algorithms. The development budget fell from KRW 3.8 billion (≈ US$2,843,000) to KRW 1.4 (≈ US$1) billion, and 12 weeks later the team filed 4 new applications reflecting the design-around.
