Patent Search
Check for prior art before filing your application, to reduce the risk of wasting time and fees on an application likely to be refused.
Who It's For
Filing without a prior search carries a high risk of refusal if a similar invention already exists, whether in Thailand or abroad.

Frequently Asked Questions
How is a patent search different from a trademark search?
A patent search checks the novelty of an invention against prior art worldwide, which is more complex than a trademark search, which only compares similarity of names/logos within the country where you're filing.
Does a search result guarantee successful registration?
No, it's not a guarantee. The search result informs the filing decision but does not guarantee that a patent will be granted. The application will ultimately be assessed by the Department of Intellectual Property based on the applicable legal requirements, the claims as filed or amended, and the prior art identified during examination.
Should I search before or after finishing development of my invention?
We recommend searching early in development, to save time and budget if a closely related prior invention already exists — so you can adjust your development direction in time.
What does the THB 8,000 patent search fee include?
It covers a list of patents/petty patents closely related to your invention, a summary of similarities and differences, a preliminary opinion on your chances of registration, and recommendations for drafting claims to avoid closely related prior art.
Does the search cover only Thailand, or worldwide?
Our team searches both the Thailand patent database and international databases, to assess the novelty of your invention against prior art worldwide, not just in Thailand.
How long does it take to get the search report?
Generally within 7 business days, though it may vary depending on the complexity of the technology and how many additional countries you want checked.
What's the difference between Freedom-to-Operate (FTO) and a Patentability Search?
A Patentability Search checks whether your invention is novel enough to be patentable. A Freedom-to-Operate (FTO) search checks whether manufacturing or selling your product would infringe someone else's still-active patent. They serve different purposes, and in some cases both may be needed.
If the search finds a very closely related patent, what should I do?
Our team will help assess your options, such as adjusting the claims to avoid the closely related point, further improving the invention to make it more clearly distinct, or assessing the risk if you still want to file as originally planned — so you can make a well-informed decision.
