Can Business Trademarks Registered by an Ex-Partner Be Recovered?
Introduction
Business partners who are also in a common-law relationship often develop a brand together, but register the trademark under only one person’s name. When the relationship ends, the registered owner may claim exclusive control over the business name, logo, customer goodwill, and related commercial assets.
The former partner’s remedies depend on several facts: who created the mark, who used it in commerce, who paid for its development and registration, whether the registration was obtained in good faith, and whether the business or mark was transferred to a corporation or other entity. Registration is important, but it does not automatically validate a registration obtained through fraud, bad faith, or unlawful appropriation.
What Law Governs Ownership of a Business Trademark?
Under Section 122 of the Intellectual Property Code, rights in a trademark are acquired through valid registration. This means that mere prior use, without more, generally does not by itself establish ownership of a trademark under the present statutory regime ([Intellectual Property Code of the Philippines (1997)](#L6.134)).
However, the registration must be valid. The Supreme Court has recognized that registration does not confer rights when it was obtained fraudulently, in bad faith, or in violation of law. A registration that knowingly appropriates another person’s established business identity remains subject to cancellation ([King, et al. v. Panciteria Lido Chinese Cuisine Co. (2026)](#J1.14)).
This distinction is important in disputes involving former partners. The registered partner may have the initial documentary advantage, but the other partner may challenge the registration by proving bad faith, prior business ownership, deceptive appropriation, or rights arising from the underlying enterprise.
Does Registration in One Partner’s Name End the Dispute?
No. Registration is strong evidence of a trademark right, but it is not conclusive where the registration itself is legally defective.
A former partner may have grounds to challenge the registration if the applicant knew that the mark belonged to, or was being used by, the jointly operated business. The first-to-file rule does not protect an applicant who acted in bad faith. A bad-faith application is unregistrable and does not confer priority or ownership ([Lim, et al. v. See (2023)](#J7.14); [Zulueta v. Cyma Greek Taverna Co. (2023)](#J11.1)).
The relevant inquiry is not simply whose name appears on the certificate. It includes whether the registration was made for the applicant’s own legitimate business or to take control of a brand developed and used by another person or by a jointly operated enterprise.
When May the Former Partner Claim the Business Name?
The former partner may have a stronger claim where the evidence shows that the mark was created and used for the benefit of a common business rather than for the personal business of the registered partner.
Relevant evidence may include:
- business permits, receipts, invoices, menus, packaging, advertisements, and social-media pages showing joint commercial use;
- proof of financial contributions to the business, branding, advertising, or trademark application;
- communications showing that the parties treated the mark as belonging to the business or to both partners;
- corporate, partnership, or accounting records identifying the business as the owner of the goodwill; and
- evidence that the registered partner knew of the other partner’s contribution but nevertheless registered the mark exclusively in an individual capacity.
The existence of a common-law relationship does not, by itself, determine trademark ownership. The dispute must be tied to the legal ownership of the business, the commercial use of the mark, the parties’ agreement, and the circumstances surrounding registration.
Protection of an Unregistered Trade Name
A trade name is treated differently from a trademark. Under Section 165.2 of the Intellectual Property Code, a trade name is protected even before, or without, registration. A subsequent use by a third party of the same or a similar trade name or mark may be unlawful if it is likely to mislead the public ([Intellectual Property Code of the Philippines (1997)](#L6.183)).
The Supreme Court has held that a trade name need not be registered with the Intellectual Property Office before its owner may seek protection. Prior use in Philippine trade or commerce is required, and likelihood of confusion is central to the claim ([Coffee Partners, Inc. v. San Francisco Coffee & Roastery, Inc. (2010)](#J3.9)).
Accordingly, a former partner may still have a claim involving the business name even if the trademark certificate is exclusively in the other partner’s name. The claim may be based on prior commercial use of the trade name, unfair appropriation of business goodwill, or the likelihood that the registered partner’s continued use will mislead customers about the identity of the enterprise.
Can a Trademark Be Cancelled for Bad Faith?
Yes. A cancellation case may be appropriate if the registration was obtained through bad faith or if the applicant was aware of another person’s prior creation, ownership, or commercial use of the mark.
Bad faith may be supported by circumstances such as:
- the applicant’s participation in creating or operating the business;
- knowledge that the mark was being used by a jointly operated enterprise;
- registration immediately before or after the relationship or business dispute ended;
- use of the other partner’s funds, business records, or goodwill to support the application; or
- an attempt to exclude the other partner from a brand that customers associated with the shared business.
The former partner should preserve evidence showing the applicant’s knowledge and intent. Bad faith is generally assessed from the surrounding circumstances, not from the certificate alone.
What Remedies Are Available?
Cancellation of the Trademark Registration
The former partner may file a petition for cancellation before the Intellectual Property Office when the registration was obtained in bad faith, violates the requirements for registrability, or interferes with an earlier legally protected right. The petition should identify the legal ground for cancellation and attach evidence of prior use, ownership, confusion, and bad faith.
Opposition to a Pending Application
If the mark has been applied for but not yet registered, a person who believes that the registration would damage their rights may file an opposition. Section 134 of the Intellectual Property Code provides this remedy ([Lim, et al. v. See (2023)](#J7.14)).
Infringement or Unfair Competition Action
An infringement action is ordinarily associated with the rights of a valid registrant. The registered owner may seek relief against unauthorized use of an identical or confusingly similar mark. The likelihood of confusion is an important consideration in determining infringement ([Isco Holding Corporation v. Nikon Corporation (2025)](#J4.8)).
Where the dispute concerns an unregistered business name, the former partner may instead rely on Section 165 of the Intellectual Property Code and pursue remedies for unlawful use of a trade name. The protection covers a trade name used in Philippine commerce even without an IPO registration ([Coffee Partners, Inc. v. San Francisco Coffee & Roastery, Inc. (2010)](#J3.9)).
Injunction and Damages
Depending on the cause of action and available proof, the claimant may seek an injunction, damages, accounting of profits, or other statutory relief. Courts may exercise jurisdiction over infringement-related claims even while a cancellation proceeding is pending, subject to the applicable jurisdictional and procedural rules ([Levi Strauss (Phils.), Inc. v. Vogue Traders Clothing Company (2005)](#J8.13)).
Corporate or Partnership Claims
If the mark was developed and used as an asset of a corporation or partnership, the dispute may also involve corporate or partnership rights. A transfer of a trade name generally follows the transfer of the enterprise or the part of the enterprise identified by that name ([Intellectual Property Code of the Philippines (1997)](#L6.183)).
The claimant may therefore need to establish that the business—not the individual registrant—owned the goodwill and commercial identity associated with the mark. The appropriate remedy may include an accounting, reconveyance of business assets, or an action concerning the ownership and disposition of partnership or corporate property.
What If the Business Was Transferred to a Corporation?
If the former partners later incorporated the business, the ownership analysis may change. The corporation may assert ownership of the mark if the business, goodwill, or branding assets were transferred to it. Evidence of transfer may include incorporation documents, board resolutions, asset-transfer agreements, accounting entries, and the corporation’s continuous use of the mark.
The Supreme Court has recognized that the ownership of a mark may be affected by the transfer of an existing business and its associated commercial identity ([Emzee Foods, Inc. v. Elarfoods, Inc. (2021)](#J12.9)). The registered individual cannot automatically treat a business asset as personal property merely because the certificate was issued in that individual’s name.
How Do Courts Assess Confusing Similarity?
When the dispute involves a competing mark or business name, courts examine whether the similarity is likely to confuse consumers as to the source, origin, or identity of the business. The dominant features of the marks may receive particular attention, especially where the marks are used for related goods or services ([Isco Holding Corporation v. Nikon Corporation (2025)](#J4.8)).
The parties should present evidence concerning the appearance and sound of the marks, the goods or services offered, the consumers involved, the channels of trade, the geographic reach of the businesses, and actual instances of confusion.
Common Scenarios
Scenario One: The Partner Registered the Joint Restaurant Name
Two partners operated a restaurant under a name created during the relationship. One partner later registered the name personally and excluded the other from the business. The excluded partner may challenge the registration if the evidence shows that the applicant knew the name belonged to the joint enterprise and registered it to appropriate the business goodwill.
Scenario Two: The Mark Was Always the Individual’s Separate Business
If the mark was created before the relationship, used exclusively for the registered partner’s separate business, and never contributed to a joint enterprise, the registration is more likely to be upheld. The former partner would need evidence of a separate agreement, contribution, transfer, or other legally recognized interest.
Scenario Three: The Business Used an Unregistered Trade Name
Even without a trademark certificate, the business may invoke trade-name protection if it can prove prior use in Philippine commerce and show that the other party’s subsequent use is likely to mislead the public. Registration in the former partner’s name does not necessarily eliminate this issue.
Evidence That Should Be Preserved
A claimant should collect and preserve the following records before filing a case:
- the trademark application, certificate, assignment documents, and correspondence with the Intellectual Property Office;
- receipts, invoices, permits, tax records, bank statements, and accounting documents;
- photographs of signage, packaging, menus, uniforms, advertisements, and online pages;
- messages, emails, and agreements discussing ownership of the business or brand; and
- customer communications or other evidence showing confusion about who owns or operates the business.
Digital evidence should be preserved in a manner that can establish authenticity, date, source, and continuity. Deleted pages, changed social-media accounts, and altered branding materials may become important evidence of control and intent.
Important Limitations
A personal relationship does not automatically create co-ownership of every business asset. The claimant must connect the relationship to a legally recognizable interest in the business, trade name, trademark, goodwill, or proceeds.
Likewise, prior use is not always enough to defeat a valid trademark registration under the present Intellectual Property Code. The stronger arguments generally involve bad faith, unlawful appropriation, trade-name protection, ownership by the business entity, or a proven agreement concerning the brand.
The precise remedy also depends on whether the registration is pending or completed, whether the mark is a trademark or trade name, whether the business remains active, and whether the claimant seeks administrative, civil, corporate, or partnership relief.
Recommended Legal Steps
- Obtain the complete trademark record, including the application, declarations, assignments, and prosecution history.
- Identify whether the dispute concerns a registered trademark, an unregistered trade name, or both.
- Prepare a chronology showing the creation, use, registration, and attempted exclusion from the business.
- Preserve documentary, testimonial, and digital evidence of joint ownership, contributions, goodwill, and the registrant’s knowledge.
- Evaluate opposition, cancellation, infringement, trade-name, unfair competition, corporate, partnership, or civil remedies according to the facts.
- Consider interim relief where continued use of the mark threatens customer confusion, loss of goodwill, or dissipation of business assets.
Conclusion
A business trademark registered under a former partner’s individual name is not automatically beyond challenge. The certificate is significant, but the registration must have been validly obtained and cannot be used as a shield for bad-faith appropriation of a jointly developed business identity.
The former partner’s strongest case will ordinarily depend on proof that the mark belonged to the enterprise, that the registrant knew of the claimant’s rights, that the registration was intended to exclude or mislead, or that the business had acquired protectable rights in the trade name through prior Philippine use. Prompt review of the trademark record and preservation of business evidence are essential before choosing between cancellation, opposition, trade-name protection, civil relief, or corporate and partnership remedies.
