Practice Area

Trademark prosecution and enforcement, handled by lawyers who litigate.

A registration is only as good as its ability to survive a challenge — and only as valuable as the willingness to enforce it. We prosecute trademarks the way we would want to defend them, and we stay with the mark once it issues.

The Approach

Prosecute with the endgame in view.

Most trademark portfolios are built as if registration were the finish line. It is not. The value of a mark is tested when a competitor adopts something close to it, when an opposer appears during the publication window, or when a registration is attacked years later for goods the owner never actually sold.

Every one of those moments turns on decisions made during prosecution — how the goods and services were identified, what was said to overcome a refusal, which specimens were submitted, and whether the use claimed was real and documented. Statements made to the examining attorney become the prosecution history, and prosecution history is evidence.

We handle prosecution with that in mind, and we stay with the mark afterward: a registration that is never policed is a registration that quietly narrows.

The path of an application. The two gold markers are the moments an owner most often loses ground — the opposition window, which runs whether or not anyone is watching for it, and the post-registration deadlines, which cancel a registration outright when missed.

01 — Clearance

Clearance & Availability

Adoption is the cheapest moment to change course and the most expensive one to get wrong. We assess availability before a mark goes to market — not merely whether an identical mark is registered, but whether the mark can be owned, defended, and used without a rebrand two years in.

✓Knockout and full availability searching.Federal register, state registrations, and common-law use, assessed for likelihood of confusion under Section 2(d) rather than string identity.
✓Inherent-distinctiveness assessment.Where the mark sits on the spectrum — fanciful, arbitrary, suggestive, descriptive, generic — and what that means for scope, cost, and enforceability.
✓Domain and marketplace screening.Whether the name is actually available in the places the business will use it, checked alongside the register rather than after filing.
✓Risk memoranda for business decisions.A candid read on adoption risk, written for the people who have to sign off on a launch.

02 — Filing

Application Strategy & Filing

The filing basis, the identification of goods and services, and the classes selected shape everything downstream — scope of protection, examination burden, cost, and vulnerability to later challenge. These are strategy decisions, not clerical ones.

✓Filing basis selection.Use in commerce under Section 1(a), intent to use under Section 1(b), foreign priority and registration under Sections 44(d) and 44(e), and Madrid Protocol extensions under Section 66(a).
✓Identification drafting.Broad enough to cover the business as it will exist, precise enough to withstand a later non-use attack — and drawn where possible from the USPTO ID Manual, which since the January 2025 fee restructuring carries a meaningful cost advantage over free-form text.
✓Specimen review before filing.Specimen refusals are among the most common and most avoidable. We review what the client actually uses in commerce before it goes to the examiner.
✓Intent-to-use management.Docketing the Statement of Use and its extensions — six months from the Notice of Allowance, extendable in six-month increments to an outside limit of thirty-six months.

03 — Examination

Office Actions & Refusals

A refusal is not a verdict. Most are answerable — but the answer becomes part of the permanent record, and an argument that clears the examiner today can narrow the mark tomorrow. We respond with both outcomes in mind.

Common grounds we address include likelihood of confusion under Section 2(d); mere descriptiveness under Section 2(e)(1); primarily geographically descriptive marks under Section 2(e)(2); primarily merely a surname under Section 2(e)(4); functionality under Section 2(e)(5); failure to function as a mark, including ornamental and merely informational use; and specimen, identification, and disclaimer requirements.

Where a mark has been refused as descriptive, we advise on the realistic paths forward — acquired distinctiveness under Section 2(f), amendment to the Supplemental Register, or reconsidering the mark itself — and on what each choice costs in future enforceability. The Supplemental Register in particular buys examination relief at a real price: those registrations cannot be recorded with Customs and carry no presumption of validity.

A deadline worth calendaring correctly. Since December 2022, most pre-registration office actions carry a three-month response period, extendable once by three months for a fee. Applications filed under Section 66(a) through the Madrid Protocol are carved out and retain the traditional six-month period with no extension available. Docketing the wrong rule is a common and unforgiving way to lose an application.

04 — Registration

Registration & Maintenance

More registrations are lost to missed deadlines than to adverse decisions. Post-registration maintenance is unforgiving, and the windows are narrow.

YEARS 5–6

Declaration of Use

A Section 8 declaration is due between the fifth and sixth anniversaries of registration, with a six-month grace period on payment of an additional fee. Madrid-based registrations use the parallel Section 71 declaration instead.

YEAR 5+

Incontestability

Where the conditions are met — Principal Register, five consecutive years of continuous use, the mark still in use, no adverse decision and no pending proceeding — a Section 15 declaration can be filed to substantially narrow the grounds on which the registration may later be attacked.

YEARS 9–10

Renewal

Renewal under Section 9 is filed in the window between the ninth and tenth anniversaries, together with the ten-year Section 8 declaration, and every ten years thereafter. Madrid registrations renew directly with WIPO instead.

Alongside the calendar, we handle assignments and chain-of-title recordation, licensing with the quality-control provisions that keep a licence from becoming a naked one, and periodic audits to identify registrations that are vulnerable, redundant, or worth pruning.

05 — Policing

Policing & Watch Services

A trademark is one of the few assets that degrades when it is ignored. Not because a statute commands the owner to patrol it — there is no such statute, and any firm that tells you otherwise is overstating the law — but because the Lanham Act attaches real consequences to inaction.

Those consequences arrive in four distinct ways, and they are worth understanding precisely:

✓Abandonment by omission.A mark is abandoned where any course of conduct of the owner — expressly including acts of omission — causes it to lose its significance as a mark.
✓Genericide.A registration may be cancelled at any time if the mark has become the generic name for the goods or services, judged by its primary significance to the relevant public.
✓A narrower scope of protection.Substantial unchallenged third-party use of similar marks is evidence that a mark is weak, which means less leverage in every dispute that follows.
✓Party-specific equitable defenses.Delay against a particular infringer can support laches, estoppel, and acquiescence — available even against an incontestable registration.

The practical answer is not to sue everyone. It is to see what is happening and choose deliberately. We set up and review watch coverage across new USPTO filings, common-law and marketplace use, domain registrations, and social media handles, and we triage what comes back — separating the genuine threats from the noise that does not warrant a letter.

06 — Enforcement

Enforcement

Enforcement is a ladder, not a switch. The right first move is usually the smallest one that solves the problem, and the wrong first move can cost the leverage of everything above it — an overreaching demand letter invites a declaratory judgment action in a forum the sender did not choose.

✓Demand letters and negotiated resolution.Calibrated to the actual strength of the mark and the actual conduct, with the downstream forum risk considered before the letter goes out. Most matters end here.
✓Marketplace and platform enforcement.Amazon Brand Registry, eBay VeRO, and the equivalent programs on other platforms. These are private contractual programs rather than statutory procedures — there is no trademark analogue to the DMCA notice-and-takedown safe harbour — and a registration is generally the price of admission.
✓Domain name disputes.UDRP proceedings, which require proof that the domain is confusingly similar, that the registrant lacks rights or legitimate interests, and that it was both registered and used in bad faith. The only remedies are transfer or cancellation; where damages matter, the Anticybersquatting Consumer Protection Act provides a federal cause of action with statutory damages of $1,000 to $100,000 per domain name.
✓Customs recordation and border seizure.A Principal Register registration may be recorded with U.S. Customs and Border Protection, which allows CBP to detain and seize infringing imports. Supplemental Register marks are expressly ineligible.
✓Counterfeiting.Federal court remedies include ex parte seizure orders, treble damages and fees for intentional use of a counterfeit mark absent extenuating circumstances, and elected statutory damages of $1,000 to $200,000 per counterfeit mark per type of goods — rising to as much as $2,000,000 where the use is found willful.

The enforcement ladder. Most infringement is resolved on the lower rungs — and the lower rungs only work if someone is watching. The point is to climb deliberately: each step preserves the options above it, and a demand letter sent badly can cost the leverage of the ones that follow.

07 — Proceedings

Contested Proceedings

When a matter does not resolve on the lower rungs, it becomes litigation — and this is the part of trademark practice where a litigation firm earns its keep.

✓Before the TTAB.Oppositions, filed within thirty days of publication in the Official Gazette and extendable on timely request; petitions to cancel on grounds including likelihood of confusion, descriptiveness, abandonment, genericness and fraud; and ex parte appeals from final refusals. The Board decides the right to register — it does not award damages or enjoin use.
✓Expungement and reexamination.The Trademark Modernization Act created ex parte proceedings to clear the register of marks never used, or not in use as of the relevant date — a comparatively economical way to remove a blocking registration.
✓In federal court.Infringement of a registered mark under Section 32; false designation of origin and unregistered trade dress under Section 43(a); dilution under Section 43(c), which is confined to marks widely recognized by the general consuming public of the United States, not merely well known within an industry.
✓Remedies.Injunctive relief, the defendant's profits, actual damages, and costs. Following Romag Fasteners v. Fossil Group (2020), willfulness is not an absolute precondition to a profits award under Section 35(a) — though the Supreme Court was explicit that the defendant's mental state remains a highly important consideration.
✓Settlement and coexistence.Consent agreements and coexistence arrangements structured so they survive contact with the examining attorney and do not create a naked licence.

08 — International

International Portfolios

Trademark rights are territorial, and the sequence of filings determines what can be claimed where. We coordinate international protection around how a business actually expands.

✓Madrid Protocol filings.International registrations designating multiple jurisdictions from a single base application, with the dependency risk of the base registration weighed openly rather than glossed over.
✓Paris Convention priority.Preserving the six-month priority window so foreign filings carry the earlier date.
✓Direct national filings and foreign counsel.Where Madrid is a poor fit — and it often is for key markets — we file nationally through vetted local counsel and manage the file.
✓Inbound U.S. representation.Foreign-domiciled applicants and registrants are required to be represented by a U.S.-licensed attorney before the USPTO. We serve as U.S. counsel for foreign firms and their clients.

Why K2K

The litigator's view of a trademark file.

K2K Law is an intellectual property boutique whose core work is high-stakes patent litigation and monetization. That background changes how we approach a trademark file rather than sitting beside it.

✓We know what a file looks like under attack.Prosecution history gets read aloud in depositions. We write it knowing that.
✓Prosecution and enforcement stay together.When an opposition, a counterfeiter, or a cancellation arrives, it stays with the same firm that built the record.
✓Portfolios are assets, not filing cabinets.We bring the same portfolio-level thinking to trademarks that we bring to patent monetization — what to keep, what to enforce, what to let go.
✓Partner attention.A boutique practice means the lawyer assessing your mark is the one who will argue for it.

Common Questions

Questions we are asked often.

Do I need a federal registration to enforce my trademark?

No. Unregistered marks and unregistered trade dress are enforceable under Section 43(a) of the Lanham Act. But registration on the Principal Register carries advantages that are difficult to replicate: nationwide constructive notice, a presumption of validity and of the owner’s exclusive right to use, eligibility to record with U.S. Customs, access to most marketplace brand-protection programs, the statutory damages regime for counterfeiting, and the possibility of incontestability after five years.

Do I have a legal duty to police my own trademark?

Not as such — and this is widely overstated. No statute obliges an owner to monitor the register or to sue every infringer. What the Lanham Act does is attach consequences to inaction: a mark can be abandoned through a course of conduct that includes acts of omission; a registration can be cancelled if the mark becomes generic; substantial unchallenged third-party use is evidence that a mark is weak and entitled to narrower protection; and delay against a particular party can support laches, estoppel, or acquiescence. The practical conclusion is the same as the mythical one — monitor and enforce selectively — but the reasoning matters when you are deciding which battles are worth fighting.

I received an office action. How long do I have?

For most applications, three months from the issue date, with a single three-month extension available for a fee. Applications filed under Section 66(a) through the Madrid Protocol are the exception: they retain a six-month response period and no extension is available. Some office actions carry shorter deadlines of their own, so the specific action controls. Missing the date results in abandonment.

Someone registered my brand as a domain name. What are my options?

Two main routes. A UDRP proceeding is faster and cheaper, but requires proving all three elements — confusing similarity, no rights or legitimate interests in the registrant, and that the domain was both registered and used in bad faith — and the only available remedies are transfer or cancellation of the domain. Where you need damages or a broader injunction, the Anticybersquatting Consumer Protection Act provides a federal cause of action with elected statutory damages of $1,000 to $100,000 per domain name.

Counterfeits of my product are being sold online. What can be done?

Usually several things at once. Marketplace brand-protection programs can remove listings quickly, though they are private contractual programs rather than statutory procedures and generally require a registration. A Principal Register registration can be recorded with U.S. Customs and Border Protection so that infringing imports are detained at the border. And federal court offers the strongest remedies for counterfeiting — ex parte seizure orders, treble damages and attorney’s fees for intentional use of a counterfeit mark absent extenuating circumstances, and elected statutory damages of up to $200,000 per counterfeit mark per type of goods, or as much as $2,000,000 where the use is found willful.

Can I register a descriptive mark?

Not on the Principal Register without more. A mark refused as merely descriptive under Section 2(e)(1) can still reach the Principal Register on a showing of acquired distinctiveness under Section 2(f), or it can be placed on the Supplemental Register while distinctiveness develops. The Supplemental Register is a real option but a limited one: no presumption of validity, no incontestability, and no eligibility for Customs recordation. Frequently the better advice at the clearance stage is to choose a stronger mark.

What happens if I license my mark without supervising the licensee?

You risk losing it. Licensing a mark without exercising adequate control over the nature and quality of the licensee’s goods or services is known as naked licensing, and it can result in abandonment of the mark entirely. The burden on a party asserting naked licensing is a stringent one, but the consequence when it is met is forfeiture — which is why quality-control provisions in a trademark licence are substantive rather than boilerplate.

Adopting a mark, or facing a refusal?

Tell us where the mark stands — pre-launch, mid-examination, opposed, or up for renewal — and we will tell you candidly what the options are.
