How should one choose a law firm in Shenzhen for U.S. trademark registration and assignment? Attorney Shen Jinlong breaks down agency pitfalls and the real fee structure: a low quote does not mean better value.

When choosing a Shenzhen law firm for U.S. trademark registration and assignment, the core point is just this: don’t simply compare quotes; look at whether the attorney has U.S. practice qualifications or a stable cooperating attorney, whether the fees are broken down into official fees and attorney/agency fees, and whether the assignment chain can be recorded with the USPTO (Assignments). A low quote often means additional charges for responding to office actions, no recordation of assignments, and no one to handle subsequent enforcement. Attorney Shen Jinlong’s team has handled a large volume of cross-border trademarks and recommends that you screen firms according to the following hard criteria.

First, check whether the attorney is eligible to deal directly with the USPTO.

The USPTO requires foreign applicants to be represented by an attorney licensed to practice in the United States and recognized by the USPTO; this is a hard rule under 37 C.F.R. §2.62. Many agents in Shenzhen simply pass the matter to a U.S. law firm, adding a layer of markup in between, so when it comes to responding to office actions, you have no idea who is actually drafting. We generally advise clients to ask directly: What is the signing attorney's USPTO registration number? Can it be verified on the USPTO website? If the other party hems and haws, when problems arise later, you won't even be able to find anyone to hold accountable. The foreign-related team at Guangdong Zhiming Law Firm directly coordinates with U.S. partner attorneys; response documents are signed by U.S. attorneys, and the chain of responsibility is clear.

A low quote doesn't mean it's a good deal; break down the cost structure first.

The USPTO official fees are fixed: TEAS Plus applications cost $250 per class, and TEAS Standard applications cost $350 per class, and these fees will not be substantially reduced in 2026. If a quote is lower than this amount, there are only two possibilities: either the official fee has not been included, or a low price is being used to attract business and the price will then be raised when responding to an Office Action. In practice, many clients first come across an advertisement for a 999 yuan US trademark package, only to discover after paying that responding to an Office Action costs another 3,000 to 5,000 yuan and that assignment recordation costs another 2,000 yuan. What you really should ask is: does the quote include the official fee, does it include one Office Action response, and does it include assignment recordation. Putting these three items in the contract is far more important than a total price that is a few hundred yuan lower.

Failure to record a trademark assignment is like buying a trademark that can fly away at any time.

A U.S. trademark assignment must be recorded with the USPTO by submitting an Assignment; otherwise, when facing third-party squatting or subsequent enforcement, your chain of title is broken. The USPTO's review period for assignment recordation is usually 1–3 months, and incomplete records will be returned. We have seen clients buy a trademark from someone else, sign only a Chinese-language assignment agreement, and fail to record it with the USPTO, only for the original rights holder to license the same trademark to a third party, leaving them extremely disadvantaged in proving their case in litigation. The law firm handling the assignment should: verify the trademark status (whether it is Live and whether Section 8/15 has been filed), draft an English assignment agreement, submit the Assignment, and track it through to completed recordation. None of these steps can be omitted, and they must be clearly stated in the quote.

The deadline for responding to an Office Action is only three months; it can be extended, but a fee is required.

After the USPTO issues an Office Action, the response deadline is 3 months, and you can request a 3-month extension, but extension fees increase by tier, with the highest tier costing over a thousand US dollars. Many low-cost agents do not include response services, and only after the Office Action arrives do they tell you that this requires an additional charge, leaving clients pressed by time with no choice but to accept. Our approach is to conduct a similarity search and goods description review before filing to reduce the likelihood of refusal; if an Office Action is actually received, the response within 3 months is included in the service fee, so clients are not asked to pay a second time. This must be confirmed before signing the contract: whether responding to an Office Action is included, and who bears the extension fee if the deadline is missed.

For trademarks of cross-border e-commerce sellers, platform registration and TRO risks must also be considered.

For Amazon sellers, getting a U.S. trademark registered is only the first step; you also need Brand Registry, otherwise when other sellers piggyback on your listing, you won’t even have a way to file a complaint. Even more troublesome is the TRO (temporary restraining order): once you’re sued for infringement, your account funds may be frozen, and settlement amounts often run from thousands to tens of thousands of dollars. When choosing a law firm, ask: Can it handle TRO settlements? Does it have U.S. litigation partner attorneys? A firm that only handles registrations and not enforcement won’t be able to help when you’re actually sued. For these services, see our U.S. and EU intellectual property legal services, covering the full process from registration to enforcement.

Choosing the wrong trademark classification will make both the subsequent assignment and renewal pitfalls.

The US uses the Nice Classification, but the goods descriptions are much more detailed than in China. If you choose the wrong class or the description is too broad, you will be required to make corrections. On assignment, if the classes in the original registration do not match the products you actually sell, the assignee will not be able to use the trademark even if they hold it. We generally advise clients to first confirm what they sell and what they may expand into over the next three years, and then decide on the classes. There is one official fee per class; choosing one more class means paying an additional fee, but choosing too few and later filing additional applications is more expensive. This kind of judgment needs to be made in light of your store links and supply chain; it is not something that is done just by filling out a form.

How can you verify whether a law firm is actually handling U.S. trademarks?

The simplest way: have the law firm provide recent USPTO application numbers, and you can check the status and attorney information yourself on the USPTO official website (TSDR system). A law firm that has actually handled cases is not afraid of being checked; if you cannot find it, be wary. Also, check whether the contracting party is a law firm. Many agencies are consulting companies, and if a dispute arises, you can only sue for breach of contract and cannot rely on lawyers' professional liability insurance. Guangdong Zhiming Law Firm is a legitimate law firm entity, and its foreign-related trademark business is handled byShen Jinlong LawyerTeam coordination: contracts and invoices are issued by the law firm. If you are also involved in markets such as the EU, Japan, and the UK, you can also look into intellectual property legal services in other countries at the same time, so as to avoid repeating the same pitfalls when filing in multiple countries.

Lawyer Shen Jinlong's practical advice: start small before going big; don't buy a bunch right away.

Many clients doing a U.S. trademark for the first time want to register all 45 classes right away, and their budget immediately balloons to tens of thousands of yuan. Our advice is to register the core classes first and expand only after sales are stable. The same applies to assignments: buy a mark you can use immediately rather than stockpiling a bunch that have not been recorded. In overseas intellectual property, the pace of portfolio planning matters more than the number of filings; for specifics, you can refer to the planning approach for overseas intellectual property. As for choosing a lawyer, check qualifications, fee breakdown, assignment recordal, and enforcement capability; sign the contract only after all four pass.
