How to Register a Trademark? (For E-Commerce)

Trademark registration is the process of officially recording your product or store name under your own name with TÜRKPATENT, giving you the exclusive legal right to use that name for 10 years. You can legally launch an e-commerce site under an unregistered name — there's no legal barrier to that — but it carries serious risk: if someone else registers the same name before you do, they can file a trademark infringement lawsuit against you, and your Trendyol or Amazon account could be suspended for "unauthorized brand use." As your sales grow and your brand gains recognition, that risk compounds — which is why it's far cheaper to file for registration while you're building your business model, not after your first orders come in. And the work isn't done once you're registered, either: other sellers can still list on the same product page at a lower price and use your brand on counterfeit goods, something Ecomiro's Buy Box Tracking module monitors in real time and alerts you about.

You can complete your trademark application entirely on your own, without paying a lawyer or trademark attorney; TÜRKPATENT's EPATS (Electronic Application System) portal accepts login via e-signature or mobile signature, and the whole process runs digitally from start to finish. Hiring a trademark attorney isn't mandatory, but it does reduce the risk of mistakes, especially around class selection and any opposition proceedings; attorneys typically charge a service fee of around 1,500-3,000 TL. If you're filing on your own, just follow the steps below in order — the whole process can be completed in a single session lasting about 1-2 hours. If you're selling as a sole proprietor, it also helps to plan your trademark registration around the same time as setting up your company, so the business owner listed on your tax certificate matches the trademark holder.

• Search for existing trademarks — Check TÜRKPATENT's online trademark search system to see whether the same or a similar name has already been registered.
• Register on EPATS and log in with e-signature — Log into the EPATS portal using your e-Devlet password, e-signature, or mobile signature, and fill in the applicant information completely.
• Upload your trademark sample and select classes — Upload an image of your logo or word mark, and select the Nice class or classes that match your line of business.
• Pay the fee — Pay the application fee online (2,820 TL, plus another 2,820 TL for each additional class) and attach the receipt to the system.
• Formal examination and Bulletin publication — The TPE completes its formal and substantive examination; applications found suitable are published in the Official Trademark Bulletin for a 2-month period.
• Opposition period and registration certificate — If no opposition is filed, or an opposition is rejected, you pay the registration certificate fee (7,010 TL) and download your certificate through EPATS.

There's no fixed answer to how many classes a trademark registration covers: under the Nice Agreement, TÜRKPATENT defines 45 classes (1-34 for goods, 35-45 for services), and how many classes you select depends entirely on what your business does. As an e-commerce seller, Class 35 is the one that belongs in almost every application, because it covers "retail/store services" — in other words, online retailing itself. On top of that, you also need to add the goods class that matches what you sell; registering only in Class 35 protects your selling service, not the product itself. In practice, most e-commerce brands get adequate protection with 2-3 classes, while brands with a wide product range may go up to 4-5.

If you pick a class that doesn't match your product category, your registration won't protect that group of goods; if you're unsure, check using the class search tool in EPATS.

According to TÜRKPATENT's current 2026 fee schedule, trademark registration for a single class totals 9,830 TL: a 2,820 TL application fee at the filing stage, plus a 7,010 TL registration certificate fee once your application is approved. These two payments are made at different times, so you pay as the process moves forward rather than all at once. Each additional class beyond the first adds another 2,820 TL fee at the filing stage; so a 3-class application pays 2,820 + 2,820 + 2,820 = 8,460 TL at filing plus 7,010 TL at registration, for a total of 15,470 TL. If you use a trademark attorney, you'll need to add their fee on top of this.

The straightforward answer to how long trademark registration takes is 6-12 months, assuming the application proceeds without complications. The TPE's formal and substantive examination takes an average of 2-3 months; applications found suitable are then published in the Official Trademark Bulletin for 2 months, during which third parties can file an opposition. If your trademark application is rejected, you have two options: request a re-examination against the TPE's decision within 2 months, or take the matter to court. Rejections usually happen because an identical or similar mark is already registered, or because the mark is descriptive/generic (for example, just the word "shoes"). An opposition or rejection can push the process well beyond the 6-12 month average, sometimes stretching it to 18-24 months.

To upload a trademark registration certificate on Trendyol, go to "Brand Application" in the Trendyol Partner panel, or the brand management section under store settings, and upload your approved TÜRKPATENT registration certificate (or application number) as a PDF; once Trendyol verifies it, you can list your products under your own brand name. On Amazon, the same certificate is a prerequisite for the Brand Registry application: you won't be accepted into Brand Registry without a registration certificate, and you'll miss out on features like A+ Content, a branded store, and advanced advertising formats. Registration isn't just a "permission slip" — it's also the gateway to managing the same brand separately across Trendyol, Hepsiburada, and Amazon; Ecomiro's Multi-Store module automates this multi-store process from a single panel, keeping your brand approvals and product matches synced across every marketplace.
