Shenzhen company trademarks hijacked, patents infringed, technology leaked? Intellectual property rights protection evaluation guide

Last month, a boss from a smart hardware company in Nanshan District, Shenzhen, came to me. His first sentence was: "Lawyer Shen, our core algorithm, which we'd been developing for two years, was taken by an engineer who just resigned. He turned around and filed a patent for it, and now he's suing us for infringement. Life just isn't worth living like this."
Before he could finish speaking, another client from Longhua sent a voice message—their best-selling lamp, which had been on the market for five years, had its design patent preemptively registered by someone else. E-commerce platforms were flooded with counterfeit products priced at only half of theirs. The experiences of these two business owners are almost a daily occurrence for tech companies in Shenzhen—intellectual property cases in the city grow by 15% each year, behind which are tens of thousands of companies paying the price for "stolen innovation."
Many clients ask me the same first question: "Lawyer, can we win this case?" But I need to correct a misconception first: in intellectual property enforcement, winning is only the first step—what matters is how you win and what you actually recover. Today, I'll break this down from three perspectives: when a Shenzhen company faces infringement of its trademarks, patents, or trade secrets, how should it choose—handle it in-house, hire a general agent, or retain a legal team that truly understands the industry?

In intellectual property cases, time is everything. For a design patent infringement case, from filing to first-instance judgment, the Shenzhen Futian Court typically takes 8-12 months; if the opposing party raises a jurisdictional objection or files for an invalidation declaration, it is not unusual for the case to drag on for two years. But every day your product remains counterfeited in the market is another day your sales channels and customers are being taken away.
Some clients spend a few thousand yuan online to buy a "rights protection package," and after the other party sends a few lawyer's letters, there's no follow-up. A lawyer's letter does have deterrent value, but it's essentially a piece of scrap paper to seasoned counterfeiters. A truly professional team will immediately apply to the court for a preliminary injunction to have the infringing products taken off the shelves without delay. In a patent infringement case involving e-cigarette accessories in Bao'an, Shenzhen, handled by Zhiming Law Firm last year, we submitted the injunction application on the very day the case was filed. The court ruled within 7 days to halt sales, helping the client preserve their sales channel in South China during the peak season—that channel's monthly revenue was 1.8 million.
Many clients have come to me holding a judgment awarding them 5 million yuan in damages, yet not a single cent has been recovered through enforcement. The opposing company had long since transferred its assets to affiliated entities, leaving only a few old computers on the books. Winning a high amount in court but being unable to collect it means all the effort was in vain.
Article 1185 of the Civil Code stipulates that where intellectual property rights are intentionally infringed upon by another person and the circumstances are serious, punitive damages may apply. However, the burden of proof for punitive damages is extremely heavy, requiring you to prove that the other party acted "intentionally" and that the circumstances were "serious." When handling cases, we lay out the chain of evidence in advance: records of private contact between the opposing party and your employees, photos from your product launch events, and even recruitment postings seeking your former employees—these are all fragments that establish "actual knowledge." In the case of the well-known Shenzhen design company being plagiarized, which Zhiming Law Firm represented, we relied on a complete chain of infringement evidence to persuade the court to apply punitive damages, ultimately awarding 3 million RMB, and by freezing the opposing party's accounts and sealing their production equipment, the judgment was fully executed within 45 days after it became effective.
In intellectual property cases, especially those involving utility models and design patents, the comparison of technical features is the core. A lawyer who only knows legal provisions but understands nothing about technical processes cannot even produce a professional comparison table for "equivalent infringement." The advantage of Zhiming Law Firm lies in the fact that Director Shen Jinlong holds a master's degree from Fudan University and served as a senior executive in a state-owned enterprise for many years, giving him a thorough understanding of how the electronics, machinery, and software industries operate.
When we take on a case, the first thing we do is not flip through statutory provisions, but rather bring engineers to the client's factory, disassemble the product, and draw up a technical feature comparison chart. In one trade secret case involving automated equipment in Longgang, Shenzhen, the opposing party argued that the technology had already been disclosed to the public. Our team spent three days squatting in the client's workshop, documenting the equipment's key parameters, tolerance fits, and temperature control curves item by item, ultimately using 127 pages of evidentiary materials to rebut the opposing party's "prior art defense" and help the client safeguard their core technology moat.
**Question:** Attorney Shen, our company's trademark was preemptively registered by an out-of-town company, and they even sent us a letter demanding we change our name. Does this mean we have no choice but to accept it?
**Answer:** Not necessarily. If the other party is guilty of malicious preemptive registration and your trademark has already gained a certain degree of influence through use, you may apply to the Trademark Review and Adjudication Board for a declaration of invalidity pursuant to Article 32 of the Trademark Law. However, there is one prerequisite: the application must be filed within five years from the date of trademark registration. Last year, we assisted a catering chain enterprise in Luohu, Shenzhen. Relying on franchise contracts, store photos, and tax payment records accumulated over three years, we successfully recovered the preemptively registered trademark—the entire process took 11 months.
If you simply want to protect your rights, hiring a litigation lawyer is enough; but if you intend to use rights protection to consolidate your market position, choose a team that understands strategy. The "Artistic Litigation" system at Zhiming Law Firm is built on the core philosophy of "sustaining the fight through litigation" — by leveraging one key lawsuit to eliminate counterfeit operations while simultaneously helping clients straighten out their combined portfolio of core trademarks, patents, and copyrights, thereby preventing secondary infringement.
This is like playing chess. Ordinary lawyers focus on how a single pawn crosses the river; we think about the overall balance of attack and defense across the entire game. Director Shen Jinlong has practiced for 26 years and has handled over 10,000 cases. His greatest strength lies in finding procedural flaws in the opposing side when at an evidentiary disadvantage, or discovering unexpected breakthroughs in the amount of compensation.
In 2023, a smart home design company in Shenzhen approached us. Their best-selling product had been 100% copied by a factory in Foshan, down to the exact same color codes on the packaging. Relying on their patent, the other party turned around and sued our client.
After taking the case, we took three actions: first, we jointly filed an invalidation declaration against the opposing party's patent with our patent agents; second, we filed a counterclaim in the Nanshan District Court in Shenzhen, alleging that the opposing party had engaged in malicious litigation; third, we simultaneously filed a complaint with the market regulation authority to initiate administrative enforcement. With these three prongs advancing in parallel, the opposing party held out for 157 days before proactively seeking a settlement. In the end, the court ruled that the opposing party pay 3 million yuan in damages and issue a public apology. This case was later recognized by the Shenzhen Lawyers Association as a typical intellectual property case of the year.
First, don't wait until a product hits the market to file a patent application. There's an old saying in Shenzhen: "File the patent before the product moves." Even a design drawing, as long as it has commercial value, should be submitted as an invention disclosure first to secure the filing date. Second, trademark registration requires a "defensive" strategy—not just registering across all 45 classes, but also registering similar names and similar designs to leave no loopholes for squatters. Third, before key employees leave, be sure to sign confidentiality agreements and non-compete clauses, and retain access records for technical documents—these are ironclad evidence in court.
Intellectual property rights protection is essentially a redistribution of commercial interests. Every day you hesitate gives your competitors more room to grow.
