A trademark and patent agency in Xiamen, on China's south-east coast. Twenty-odd years of it, mostly for manufacturers — which is why we are unusually comfortable with hardware.
Xiamen is a manufacturing city. The companies on our client list make LED chips, relays, optical lenses, medical implants, industrial tungsten, buses. That shapes a firm: our patent attorneys read drawings, and our trademark practice is built around goods that exist rather than services that are described.
It also explains how foreign clients found us. Linde and Bridgelux did not come to Xiamen for the scenery — they came because things they care about are made or sold here, and a company with no place of business in China must appoint a Chinese agency to protect them. That is the business we are in.
Six things a foreign brand actually cares about when it hands its rights to an agency it has never met.
Trademark, patent, copyright, enforcement and portfolio work — filed and defended from a single firm in China, so nothing falls between two providers.
Our patent attorneys work across mechanical, electronics, chemistry and biotech. They read drawings and claims — which is why our drafting clears examination.
Pre-filing searches and freedom-to-operate analysis, so you know the odds — and the obstacles — before you commit budget.
The official CNIPA fees are public and we show them line by line. Our own service fee is quoted per matter, in writing, before you engage us — nothing bundled, no hidden charges.
Watch services, brand monitoring and portfolio planning after the grant. Most of our foreign clients stay on a standing retainer.
A CNIPA-registered patent agency (code 35218) and trademark agency, with an in-house law firm for litigation. Every claim on this page is checkable.
Figures as stated by the firm. We have not padded them and we have not published a “founded in” year on the front page, for the reason set out below.
Firms in this industry like to claim the oldest date they can defend. We would rather show you the whole sequence and let you decide which number means something, because you can look all of this up anyway.

The present legal entity — 厦门市精诚新创知识产权代理有限公司 — dates from 2013. The predecessor practices date from 2003 and 2006. So “twenty-odd years” describes the practice; 2013 describes the company. Both are true and they are not the same claim.

As listed in the firm’s Chinese brochure; we have not gone back to each issuing body to re-confirm every line. The brochure carries more of them — association memberships, science-park tenant listings, an SME growth award — which we have left off this page because they need too much local context to mean anything from outside China.
Six functions. The one to look at first is at the top.
The foreign-related department is a standing department, not a desk someone staffs when a file arrives from overseas. It has its own groups for filing practice, legal work and trademarks, under a director who spent six years running IP inside listed manufacturers before joining us. If you instruct us from outside China, that is who your matter sits with — and the patent or trademark specialists above do the substantive work behind them.
The partners who lead the work — named, with their qualifications — and the firm’s registered patent attorneys are listed on a dedicated page.

Anonymised where we don’t have consent to name the client. They range from turning back a foreign patent-holder’s claim to winning a trademark fight on appeal and mapping a technology field before a client filed into it — the capability a foreign brand is buying, whoever the client happened to be.
A Xiamen technology company received an infringement warning from a major US automotive manufacturer. We compared the asserted patents against the product, judged the risk real, then examined the patents' own validity and found prior art capable of undermining them.
Outcome — Armed with that analysis, the client negotiated a favourable settlement and avoided the loss — then retained us for a full wireless-charging patent-risk review.
Chinese client vs US patent-holder
The client held five registered marks in Class 25 (footwear). A seller offered look-alike goods through a marketplace storefront, and the platform did not act on the cease-and-desist letter. We sued both.
Outcome — The court ordered the infringer to stop and pay damages and the marketplace to close the store, with the platform jointly liable. The judgment was upheld on appeal.
Chinese client vs domestic infringer + marketplace
Three-phase induction motors are specified for peak load and then spend most of their life at part load, where power factor falls away and energy is wasted. Working for an induction-motor manufacturer in Fuzhou, we took the field apart patent by patent: where the Chinese and foreign filings sit, who holds them, which routes are already fenced off, and where the research is actually moving — winding and connection design, starting and braking, structural changes for heat dissipation and high-temperature service, forced-air cooling that can be maintained in the field, and rare-earth permanent-magnet materials.
Outcome — The study set the direction for the client's own programme — NVH performance, and the efficiency gains needed for the IE4 and IE5 classes — and for the patent filings that came out of it. Intenova is named on the project record as the patent-navigation service provider.

A solenoid valve inside diagnostic and treatment equipment is a small component with a long patent trail. We decomposed the technology, mapped where the Chinese and foreign filings sit, went through the litigation the field has already produced, identified the points where claims cross and infringement becomes possible, and read the competitors' portfolios for direction — the trend, the research hotspots, and the technical barriers already standing.
Outcome — The deliverable was a filing strategy built on what the field already owns rather than on guesswork, and a documented view of the IP risk that travels with an electric fluid-control product sold across borders. Intenova is named on the project record as the patent-navigation service provider.

Head office relocated to Software Park Phase III, Jimei District, in 2021. An associated law firm, Fujian Jingya (福建精亚律师事务所), was established in 2023 as a separate legal entity — Chinese law requires patent agencies and law firms to be separate.
