As brands become central business assets, founders and executives looking to secure trademark rights often find themselves navigating clearance risk, descriptiveness and likelihood-of-confusion refusals, and the deadlines that decide whether a registration ever issues.
Building a brand is expensive, and the legal right to it is rarely automatic. A name can clear a quick web search and still collide with a prior registration, draw a likelihood-of-confusion refusal, or stall on a specimen objection that costs months to resolve. Trademark prosecution — the work of clearing a mark, filing the application, responding to the United States Patent and Trademark Office (USPTO), and carrying the mark through to registration — is where those outcomes are won or lost. NK Patent Law handles that work for technology-driven companies and the brands they build.
NK Patent Law represents companies and inventors in patent prosecution and intellectual property strategy, and trademark prosecution is a core part of that practice. Because trademark rights in the United States are governed by federal law under the Lanham Act, NK Patent Law represents clients before the USPTO regardless of where they are located.
Our team has helped clients secure 1,000+ registered trademarks and 2,100+ issued patents, working with companies in 36 U.S. states and coordinating international filings across 27 countries. That portfolio spans software and consumer-technology brands as well as the product names, logos, and slogans that go to market alongside them.

Trademark protection across the prosecution lifecycle
Trademark prosecution is a sequence, not a single filing. NK Patent Law works with clients across the full lifecycle:
- Clearance and availability searching — knockout and comprehensive searches to assess whether a proposed mark is available and to surface likelihood-of-confusion risk before money goes into the brand.
- Application strategy and filing — selecting the correct filing basis, including use-in-commerce applications under Section 1(a) and intent-to-use applications under Section 1(b) of the Lanham Act, and identifying the right goods and services and international classes.
- Office Action responses — preparing arguments and evidence to overcome refusals issued by the USPTO Examining Attorney, including likelihood-of-confusion and descriptiveness rejections.
- Statements of use and registration — for intent-to-use applications, filing the statement of use once the mark is in commerce and carrying the application through to registration.
- Post-registration maintenance — Sections 8 and 15 declarations, renewals, and the docketing required to keep registrations alive.
- Opposition and cancellation proceedings — initiating and defending domestic and foreign opposition and cancellation proceedings before the Trademark Trial and Appeal Board (TTAB) and foreign equivalents.
- Portfolio management — coordinating families of marks across product lines and jurisdictions so the portfolio reflects how the business actually operates.

Examination strategy at the USPTO
Most trademark applications that fail do so for predictable reasons, and most refusals are answerable with the right argument and evidence. NK Patent Law’s trademark attorneys prepare applications with examination in mind:
- Likelihood of confusion (Section 2(d), 15 U.S.C. § 1052(d)). The most common substantive refusal. We assess the DuPont factors — similarity of the marks, relatedness of the goods and services, and channels of trade — at the clearance stage, so the risk is understood before filing rather than discovered in an Office Action.
- Descriptiveness and genericness (Section 2(e)). Marks that merely describe a feature of the goods face refusal. We counsel clients on where a proposed mark sits on the distinctiveness spectrum and, where appropriate, build a record for acquired distinctiveness under Section 2(f).
- Specimen and use refusals. Many applications stall on specimens that do not show the mark used in commerce as filed. We help clients select specimens that meet the USPTO’s requirements the first time.
- Identification and classification. Goods and services that are too broad, too vague, or misclassified invite refusals and amendments. Precise identifications reduce friction and protect the scope that matters.
International filing
Trademark rights are territorial — a U.S. registration does not protect a mark abroad, and many foreign systems are first-to-file rather than use-based, so filing sequence and timing matter. NK Patent Law coordinates foreign filing through the Madrid Protocol, Paris Convention priority, and direct national filings.

Portfolio management, licensing, and transactions
A trademark portfolio is a business asset, and it is evaluated like one in financings, licensing deals, and acquisitions. NK Patent Law helps clients:
- Manage and docket renewal and maintenance deadlines across a portfolio of marks.
- Evaluate in-licensed and out-licensed marks and the rights that come with them.
- Address trademark considerations in due diligence for acquisitions, licensing, and financings, alongside the firm’s patent due diligence work.
Technical backgrounds
Our attorneys hold engineering and science degrees and focus on patent prosecution and intellectual property strategy for technology-driven companies. For brand owners, that depth means trademark work is coordinated directly with the firm’s patent prosecution practice on the same underlying technology, rather than treated as a separate workstream. Product names, software platforms, and hardware brands often need protection in the same markets where the technology is patented, and aligning both produces stronger protection at lower overall cost.
