Apple Wins iBooks Trademark Infringement Lawsuit

The United States District Court for the Southern District of New York granted Apple’s motion for summary judgment and dismissed a trademark infringement claim brought against it by Black Tower Press, the publisher of “ibooks” branded books. The decision reinforced the importance of federal trademark registration and the role of actual marketplace confusion in trademark infringement cases—and offered important lessons for both established brand holders and companies with unregistered common law marks.

The Dispute: Two “iBooks” in the Marketplace

Black Tower Press and its predecessor had published books under the “ibooks” brand since 1999—predating Apple’s iBooks application, which launched in 2010 as a platform for purchasing and reading electronic books and digital content on Apple devices. Despite the earlier start date, Black Tower had never obtained federal trademark registration for its ibooks brand.

Apple, by contrast, obtained a federal trademark registration for “iBooks” in 2010 when it launched its digital reading application. With a registered mark, Apple had nationwide priority as of its filing date for all the goods and services covered in the registration. Black Tower argued that its years of prior use in the marketplace—while unregistered—gave it superior common law rights that should prevail over Apple’s registered mark.

Why Common Law Rights Are Not Enough

Black Tower’s case illustrates the critical limitation of unregistered common law trademark rights. Common law trademark rights arise through use in commerce, not registration, and they provide genuine legal protection. However, common law rights have a significant limitation: they extend only to the geographic area where the mark has actually been used and achieved recognition. A publisher selling books under the ibooks name primarily in certain regions cannot claim nationwide common law rights—only rights in the specific territories where the mark has been continuously used and consumers have come to associate the mark with that publisher.

Federal registration, by contrast, provides constructive nationwide notice and creates a presumption of nationwide priority as of the filing date. Even if another party was using the same or similar mark in some parts of the country before the registration issued, the registrant’s rights are presumed nationwide—except in areas where the prior user can prove actual use before the registrant’s filing date.

The Summary Judgment Decision

The court granted summary judgment for Apple on two grounds. First, Black Tower did not present sufficient evidence that Apple’s use of “iBooks” would be likely to confuse consumers about the source or affiliation of the products. The court considered the standard multi-factor likelihood of confusion analysis, including the distinctiveness of the respective marks, the proximity of the goods (book publishing versus a digital reading application), the sophistication of consumers, and the evidence (or lack thereof) of actual confusion in the marketplace.

Second, Apple’s registered trademark carried legal weight that Black Tower’s unregistered common law rights could not easily overcome. Without registration, Black Tower lacked the presumptions of validity and nationwide priority that attach to a registered mark. Black Tower’s unregistered rights, whatever their scope, did not give it the legal footing to challenge Apple’s registered iBooks mark on a nationwide basis.

Lessons for Brand Owners

Register Early

The most important lesson from the iBooks case is to register your trademark as early as possible. Black Tower’s failure to register its ibooks mark despite over a decade of use left the company vulnerable to precisely the scenario that occurred: a well-funded competitor launching a product under a substantially similar name and obtaining federal registration before Black Tower acted. Federal registration is not expensive, and the rights it creates are far more powerful than unregistered common law rights.

Document Your Use

If you are operating with an unregistered mark and believe you have prior use rights in specific geographic areas, document that use meticulously: sales records, advertising materials, invoices, and customer correspondence from the earliest possible dates. This documentation supports a common law priority claim and creates the evidentiary record needed to establish prior use in specific territories.

Monitor the Trademark Register

Trademark monitoring services can alert you when applications for marks similar to yours are filed at the USPTO. This notice gives you the opportunity to oppose the application during the 30-day opposition period before registration issues—a far more cost-effective path than challenging a registered mark after the fact.

Trademark Infringement Analysis: The Likelihood of Confusion Standard

Apple’s victory in the iBooks trademark dispute illustrates how courts and the TTAB analyze likelihood of confusion under 15 U.S.C. § 1052(d), which bars registration of a mark that is confusingly similar to a previously registered mark when used on related goods or services. The likelihood of confusion analysis under federal trademark law focuses on whether consumers are likely to be confused as to the source, affiliation, or sponsorship of goods or services bearing the respective marks. Courts apply multi-factor tests — most famously the DuPont factors articulated in In re E.I. du Pont de Nemours & Co., 476 F.2d 1357 (CCPA 1973) — to assess the probability of confusion.

Key DuPont factors include: the similarity of the marks in appearance, sound, connotation, and commercial impression; the relatedness of the goods or services; the similarity of established trade channels; the conditions under which purchases are made; the fame of the prior mark; the number and nature of similar marks on related goods; the existence of actual confusion; and the variety of goods on which the prior mark is used. No single factor is dispositive, but the similarity of the marks and the relatedness of the goods are typically the most influential.

For well-known marks like Apple’s brand portfolio, the “fame” factor carries significant weight. Famous marks — those that are widely recognized by the general consuming public — enjoy broader protection against dilution as well as infringement. The Federal Trademark Dilution Revision Act, 15 U.S.C. § 1125(c), protects famous marks against uses that blur the distinctiveness of the mark or tarnish its reputation, even where no likelihood of confusion exists.

Lessons from Trademark Disputes for App and Platform Developers

The iBooks litigation and similar disputes involving major technology brands carry practical lessons for app developers and platform operators who name their products. Clearance search is not optional — before investing in a product name or brand, a comprehensive trademark search covering registered marks, pending applications, and common-law uses in the relevant classes of goods and services is essential. Launching under a name that infringes a registered mark exposes the developer to injunctive relief that may require a costly rebrand mid-launch, disgorgement of profits, and attorney’s fees in exceptional cases.

Where coexistence is possible — because the marks are used on genuinely distinct goods in separate channels with no realistic consumer overlap — a coexistence agreement or consent agreement can allow both parties to use similar marks without litigation. These agreements are a routine part of trademark practice and, when properly drafted, are recognized by the USPTO as evidence bearing on likelihood of confusion in subsequent proceedings.
