Definition and significance of defensive marks
Defensive marks are designations commonly used in trademark law for registered trademarks that are filed and maintained primarily not for the purpose of active use in commercial transactions, but to protect existing trademark rights or trade names. The objective of filing and using a defensive mark is particularly to ward off potential infringements of intellectual property rights or to prevent trademark conflicts caused by third parties. Defensive marks are closely related to issues of securing intellectual property rights, strategic portfolio management of trademarks, and aspects of competition law.
Legal classification of defensive marks
Trademark law fundamentals
The filing of a defensive mark is governed by the general principles of trademark law, particularly according to the Trademark Act (MarkenG). Pursuant to Section 4 MarkenG, trademark protection arises through registration of the mark in the register kept by the German Patent and Trademark Office (DPMA), through use of a mark in commercial transactions, or through notorious reputation.
In contrast to so-called use-based marks, where original use in commercial transactions and distinctiveness for goods or services is paramount, the defensive mark is not necessarily actively used. Rather, it serves to support existing trademarks and safeguard them against similarly designed filings by third parties.
Scope of protection and defensive function
The protection of a defensive mark extends to the goods and services registered. The owner can take action against younger identical or confusingly similar marks and thereby prevent third-party filings from diluting their own mark or restricting existing rights.
Defensive marks in the context of trade name law
Relationship to trade names
Trade names enjoy protection for commercial transactions according to Section 5 MarkenG. If trademarks are additionally filed as defensive marks to safeguard trade names, this is intended to increase and complement the scope of protection under trade name law. Here, defensive marks often serve the aim of obtaining a broader spectrum of protection rights, especially when different classes of goods or services are involved.
Distinction from offensive marks
Unlike defensive marks, offensive marks are characterized by being actively used at the core of the brand, particularly with the intention to enforce in the market. Defensive marks are primarily geared toward defense, as they are filed to protect existing rights and do not necessarily serve to further their own product or service line.
Requirements and admissibility of defensive marks
Registration requirements
The same legal requirements apply to the registration of a defensive mark as for other trademarks. The necessary requirements, such as distinctiveness (§ 8(2) no. 1 MarkenG) and the absence of grounds for refusal (§ 8 MarkenG), must be met. The German Patent and Trademark Office does not examine whether there is a concrete intention to use behind the registration, as long as the other legal requirements are fulfilled.
Obligation to use and cancellation
An essential aspect of trademark law is the so-called obligation to use. According to Section 26 MarkenG, a trademark can generally only be effectively enforced if it is put to genuine use within five years after registration. For defensive marks, this means that they, too, are subject to the risk of cancellation for non-use (§ 49 MarkenG) after the five-year grace period expires. A purely defensive filing without actual use in the course of trade is not suitable in the long term to maintain protection.
Case law and practice regarding defensive marks
Treatment by courts and authorities
Supreme court case law, such as from the Federal Court of Justice (BGH), emphasizes the principle of equal treatment for all trademarks, regardless of the underlying intent for the application. The mere defensive purpose is not inadmissible in itself; however, each individual case examines whether a register mark is genuinely used and what role it plays in legal transactions.
In particular, in cancellation proceedings it is thoroughly examined whether the defensive mark was actually the object of serious use or whether the application was solely made to hinder third parties or to block rights. Such abusive filings for intellectual property rights can constitute unfair abuse under competition law.
Filing defensive trademarks as part of a protection rights strategy
Portfolio management and extension of scope of protection
In trademark portfolio management, defensive marks play an important role. Companies use them to secure the scope of protection for their core brands, to safeguard against circumvention applications, or to strategically close gaps. Filing a defensive mark can cover various classes and enable parallel protection rights in different countries or regions.
International aspects
Companies operating internationally often secure their core brands with defensive marks in relevant markets. Filing a defensive mark under the Madrid Agreement (MMA) or through the WIPO international system can be used specifically to avoid trademark conflicts in various jurisdictions.
Critical appraisal and limits of the defensive mark concept
Competition conflicts and risk of abuse
The filing of defensive marks is sometimes criticized, especially if a mark is used solely to block third parties. It is the responsibility of authorities and courts to differentiate in each case between a legitimate intellectual property strategy and abusive creation of monopolies. So-called abuse of rights can have legal consequences and lead to invalidity or cancellation of the trademark.
Legal restrictions due to the obligation to use
The obligation to use acts as a key corrective to clean the register of actually used trademarks and to counter so-called paper trademarks, to which defensive marks may belong. Genuine use is thus a precondition for the sustainability of trademark protection.

Summary
Defensive marks are an important instrument in trademark and trade name law, helping companies strategically protect existing rights and prevent trademark conflicts in advance. However, they are subject to the same requirements and restrictions as any registered trademark, particularly the obligation to use. Long-term effectiveness is only achieved if the defensive mark is actually put to genuine use. Abusive filing practices can lead to legal consequences such as cancellation or invalidity of the right. Thus, defensive marks are a significant but legally clearly defined element of modern intellectual property management.
Frequently asked questions
When are defensive marks legally relevant?
Defensive marks become relevant under German trademark law whenever a company files or maintains a mark not to actively use it for goods or services, but to use it as a protective measure against the registration or use of similar marks by third parties. Their legal relevance arises particularly in opposition and cancellation proceedings before the German Patent and Trademark Office (DPMA) or courts, as defensive marks are used purely as protective measures, requiring assessment of whether there is trademark use within the meaning of the Trademark Act (MarkenG). They are especially relevant when third parties attempt to register or use similar marks, and the owner of the defensive mark responds with infringement, cease and desist, or opposition claims.
What legal requirements must defensive marks meet to be protected?
Defensive marks basically have to fulfill the general requirements of trademark law to enjoy protection. In particular, this includes distinctiveness in accordance with § 8 MarkenG and the absence of absolute grounds for refusal. Furthermore, it is crucial that the trademark owner can demonstrate at least some intention to use: If filing or maintaining is based solely on protective motives without the intention to use, this may be considered an abuse of rights in the event of a conflict. Courts often examine whether the application was made exclusively on a ‘speculative’ or ‘defensive’ basis without any serious intent to use. According to § 49 MarkenG, this can result in the mark being cancelled if non-use for five years is proven.
Can defensive marks be enforced in opposition proceedings?
In opposition proceedings under § 42 MarkenG, a trademark registered as a defensive mark can generally also be asserted against a newly registered conflicting mark. However, the office regularly checks in the proceedings whether the opposing mark has been seriously used, or whether proof of use can be provided on request (§ 43 MarkenG). If it becomes clear that the older mark is a defensive mark that has never been used, the opposition may fail if the non-use defense is successfully raised.
What risks are involved in registering defensive marks?
The main legal risk is that defensive marks may be cancelled by competitors and other third parties under § 49 MarkenG if no serious use can be demonstrated within a period of five years. In addition, trademark owners risk that applications for defensive marks could be classified as made in bad faith within the meaning of § 8(2) no. 10 MarkenG, if it can be proven that they serve solely to block competitor applications and not for their own trade in goods or services. In the worst case, trademark claims for cancellation, damages, and even court costs may arise.
Are there overlaps with copyright or competition law when using defensive marks?
In connection with defensive marks, especially when well-known trade names or titles of works are registered, aspects of competition law (e.g., unfair competition pursuant to § 4 UWG) or copyright issues (e.g., when designing logos) may also be affected. Trademarks filed solely to hinder third parties may be considered anti-competitive, especially where there is demonstrable intent to cause harm or abuse of rights. Copyright overlaps arise if the defensive mark is also a work protected by copyright or conflicts with such a work.
Under what conditions can a third party apply for deletion of a defensive mark?
According to § 49(1) MarkenG, any third party may file a request for deletion of a mark with the DPMA for non-use if, after more than five years from registration, there has been no genuine trademark use for the protected goods or services. The respondent must then provide appropriate evidence of genuine use. Otherwise, the defensive mark will be deleted from the trademark register. The burden of presentation and proof lies with the trademark owner; even preparatory actions or minor uses are insufficient unless there is serious participation in commercial transactions.
What special provisions apply to defensive marks in European trademark law?
In European trademark law, particularly with regard to EU trademarks, similar regulations apply as in German law. There too, a trademark is subject to use requirements and can be cancelled for non-use after a period of five years (Art. 58, 61 EUTMR – European Union Trademark Regulation). Defensive filings often occur to prepare for international competition. Courts of the European Court of Justice (ECJ) examine in such cases whether there was a serious intention to use and whether the mark was used in commercial transactions. Here too, there is the risk of cancellation and other legal consequences if the use remains purely defensive.
