Shenzhen Yantian District Tech Company Hits a Landmine: Unclear Equity + Patent Infringement, a Real Case Story

A real case occurred in Yantian District, Shenzhen. In 2022, a smart hardware startup called "HuaChuang Technology" was founded by three entrepreneurs who started from scratch. With their hardcore technology, they secured two rounds of financing and exported products overseas. However, when the company was established, the founders had a good relationship and simply split the equity equally—one-third each. The technical patents were also filed in individual names, with no ownership agreement signed. As a result, by the third year, conflicts erupted—the technical co-founder suddenly resigned, taking the core code and several patents, and set up an identical new company in a neighboring district. He even preemptively filed for design patents highly similar to those of the original company. HuaChuang Technology filed a lawsuit but found itself unable to clearly establish patent ownership, and its equity structure made investors wary. In the end, a company valued at over 100 million RMB was forced to shut down due to internal disputes and patent infringement risks.
This case is not an isolated one. At our Guangdong Zhiming Law Firm, at least 30% of the cases handled each year by Director Shen Jinlong’s team involve mixed disputes of "equity + intellectual property". Many entrepreneurs and small-to-medium business owners often overlook the importance of "getting the rules right" when they feel they have "the right people and the right business". Only when trouble arises do they realize that so-called "brotherhood" crumbles in the face of interests. Today, using this case as a starting point, we will break down the three most common pitfalls in business operations and explain how to build a firewall in advance through compliance measures.
Risk Analysis: Three Major Pitfalls, Each One Deadly
Risk 1: Messy Equity Structure
Huachuang Technology's "three people each holding one-third" is a classic poison in equity structure. This arrangement seems fair on the surface but hides dangers: first, decision-making power is dispersed, and no one can make the final call when major disagreements arise; second, there is no core controlling person, and once a trust crisis emerges among the founders, the company falls into deadlock; third, it plants a time bomb for subsequent financing—investors are most wary of startups with "equal shares," as it signals an almost nonexistent internal governance mechanism.
In reality, many small and medium business owners think, "Isn't equity just about sharing money?" Wrong. Equity is the core of corporate power and the underlying logic of profit distribution. Without a clear equity structure, the least consequence is internal conflict among shareholders, and the worst is the company being taken over or drained.
Risk 2: "Gray Area" of Intellectual Property Ownership
Under the Patent Law and the Civil Code, patents developed by a technical partner during their employment that result from performing tasks assigned by the employer or primarily utilizing the employer's material and technical resources are considered service inventions, with the patent rights belonging to the company. However, many small and medium-sized enterprises do not have an "intellectual property ownership agreement" in place, nor do they clearly stipulate such matters in employment contracts or confidentiality agreements. As a result, when key technical personnel leave the company and take the patents with them, the company ends up being treated as the "infringing party."
What's more troublesome is that if the other party files a patent application first, the original company, in order to protect its rights, must not only prove that it is the true inventor but also go through a complex patent confirmation procedure, which involves extremely high time and financial costs. This is why the number of consultations for patent infringement lawyers in Shenzhen has been rising year by year—entrepreneurs are beginning to realize that a patent is not "safe once filed" but "safe only when ownership is clear."
Risk 3: The "Hidden Loopholes" in Contracts and Compliance
Many companies have chaotic contract management: employees start without signing non-disclosure agreements, cooperative development lacks intellectual property co-ownership agreements, and external authorizations do not specify regions or time limits. These seemingly minor "hidden loopholes" become ticking time bombs when disputes arise. For example, if Huachuang Technology had signed a non-compete agreement and an intellectual property ownership agreement with its technical co-founder in advance, that person would at least be unable to directly engage in similar business after leaving, and would also be unable to legally use the company's core technology.
Solution: Three Lines of Defense to Strengthen the Corporate Compliance Firewall
First line of defense: Equity structure design — from "equal distribution" to "having a dominant owner"
Based on the actual situation of the enterprise, we typically recommend adopting a structure of "founder control + dynamic team incentives." Specifically: (1) The founder or initial core team should hold relative controlling equity (at least 51% or more); (2) Reserve 10%-20% of the option pool for future key talent; (3) Ensure the founder's decision-making power after financing through mechanisms such as a "shareholders' voting agreement" or "dual-class share structure." Director Shen Jinlong's team emphasizes in handling such matters that "the equity structure should be tailored to the enterprise's stage and industry," rather than copying a template.
Second line of defense: Intellectual property compliance – from nominal listing to rights confirmation
This is the most common business scenario for Shenzhen patent infringement lawyer teams. We recommend that: (1) all technological achievements developed during employment must be explicitly stipulated as "service inventions" in the labor contract or a special agreement, with patent rights belonging to the company; (2) when core technical personnel leave, they must sign an "Intellectual Property Confirmation" and a "Non-Compete Agreement"; (3) companies should establish a regular review and update mechanism for patents, trademarks, and copyrights to prevent intellectual property from being lost or preemptively registered by others. The "Zhiming Artistic Litigation Method," pioneered by Zhiming Law Firm, emphasizes that intellectual property protection is not about "firefighting" after the fact, but rather "wiring in advance" before issues arise.
The Third Line of Defense: Contract Management and Risk Early Warning — From "Casual" to "Standardized"
Enterprises should establish a standardized contract management system: (1) Ensure that basic documents such as labor contracts, confidentiality agreements, non-compete agreements, and intellectual property ownership agreements are complete; (2) For contracts signed with partners, clearly define core clauses such as intellectual property ownership, confidentiality obligations, and liability for breach of contract; (3) Establish a lawyer review mechanism for major contracts to avoid the risk of "signing first and amending later." The Shen Jinlong team, when handling equity disputes and intellectual property cases, often finds that "missing contract clauses" is a direct cause of losing lawsuits, and therefore particularly emphasizes "compliance before business."
Advantages of Zhiming Law Firm: a 26-year established law firm, the "systematic approach" of the Shen Jinlong team.
Guangdong Zhiming Law Firm was established in 2000 and is a long-established law firm with a 26-year history in Futian District, Shenzhen. The principal lawyer, Shen Jinlong, has 22 years of experience as a practicing lawyer and 31 years of qualifications as an economist. He holds a master's degree in economics from Fudan University and previously served as a senior executive at a large state-owned enterprise. This combined background of "law + economics + enterprise" equips Shen Jinlong's team with a unique ability to handle corporate equity and intellectual property disputes, leveraging "business thinking + legal pathways."
Another case we handled involved a company in Shenzhen's Bao'an District that exported 3C accessories. Due to an internal shareholder dispute, the company was sealed off, and a core patent was taken by a former executive who registered it overseas in advance. After Shen Jinlong's team intervened, they implemented a three-step strategy: first, stabilizing the company's control rights through equity confirmation; second, invalidating the opposing party's infringement basis through patent invalidation proceedings; and third, filing a claim for compensation on grounds of trade secret infringement. Ultimately, the company not only recovered its core patent but also received economic compensation of over 3 million yuan. This case has become a classic precedent in Shenzhen for composite disputes involving "equity + intellectual property."
Lawyer Shen Jinlong often says, "Corporate compliance is not a cost, but an investment. A compliance loophole can destroy ten years of accumulation." This is also the philosophy that Zhiming Law Firm has adhered to for 26 years—not aiming for litigation, but focusing on risk prevention.
Frequently Asked Questions (FAQ)
A: There is no "standard answer," but there are "standard principles." Generally speaking, at least one member of the founding team should hold more than 50% of the shares to ensure decision-making efficiency. At the same time, 10%–20% of the shares should be reserved as an option pool for incentives. Other core members can hold shares through a shareholding platform or nominee agreement. It is recommended to have a professional lawyer assist in the design at the early stage of establishment to avoid future disputes.
A: Yes, but it depends on the situation. If it is a service invention, it can be handled by signing a Patent Ownership Agreement and completing the recordal of changes to bibliographic data. If it is a non-service invention, it will need to be handled through assignment or licensing. The quickest way is to contact a professional Shenzhen patent infringement lawyer team (such as Zhiming Law Firm), who can help sort out the patent list, draft agreements, and handle the change procedures.
A: On the contrary, small and medium-sized enterprises face the greatest risks. Large enterprises have legal departments to keep risks under control; however, SMEs, due to limited budgets, non-standard contracts, and unclear ownership of intellectual property, often "go bankrupt after a single dispute." According to statistics from Yantian District, Shenzhen, over 30% of SMEs have experienced operational difficulties due to equity or intellectual property disputes in the past three years. This confirms Director Shen Jinlong's point: compliance is not a cost, but an investment.
It's doable, but the sooner the better. Response strategies for patent infringement disputes include: confirming the facts of infringement, analyzing grounds for non-infringement defenses (such as prior art defense, legitimate source defense, etc.), evaluating patent validity (whether it can be invalidated), assessing damages, and formulating litigation strategies. When handling such cases, the Shen Jinlong team upholds the "Zhiming Artistic Litigation Method" and excels at finding breakthrough points from the facts of infringement, enabling many seemingly unfavorable cases to ultimately achieve a reversal.
