For International Legal Counsel · U.S. Trademark Referral Partnerships
Kaleidoscope Law is founded by Kay Dindayal — a former USPTO Trademark Examining Attorney who spent a decade inside the government office that decides which brand names get protected and which ones don't. That institutional knowledge is what every Kaleidoscope engagement is built on.
Here is what it means for the work you refer.
Since August 2019, the USPTO has legally required all foreign-domiciled applicants to be represented by a licensed U.S. attorney. Your clients already need a U.S. attorney of record. The only question is whether that attorney is the right one.
Most U.S. trademark firms understand the filing process from the outside — submitting applications, responding to rejections, working the system as petitioners. That is the standard.
Kaleidoscope Law is different. The firm is founded and led by Kay Dindayal, who spent ten years as a USPTO Examining Attorney — the government official who reads every incoming application and decides which ones proceed to registration and which receive a rejection letter. She wrote those letters. She knows the precise criteria, the automated AI conflict-scanning tools, and the registrability judgments that no public manual captures.
Before founding Kaleidoscope Law, Kay held roles in legal research and contractual compliance at Bloomberg LP, and built her analytical foundation as an accountant at a multinational management consulting firm. She brings 20 years of corporate, financial, and legal experience — including 14 years of legal practice — to every engagement.

Every application is prepared using the internal standards Kay applied as a government reviewer — the precise language, category construction, and description approach that clears examination. Not approximated from the outside. Known from a decade of making those calls.
Non-substantive office actions — identification amendments, disclaimers, classification corrections, specimen issues — are resolved as part of the engagement at no additional fee. Substantive refusals are accepted as a separate engagement and only on matters Kaleidoscope assesses at 65% or higher likelihood of success on the merits. Kay has personally written hundreds of these refusals as a USPTO Examining Attorney — and that selectivity is what makes the engagement worth taking.
Kay prepares every application to qualify for the lower $350 filing tier where eligible — saving clients $200 per class before the filing is even submitted. She spent a decade deciding whether applications met that standard.
Since mid-2025, the USPTO has deployed automated conflict-scanning tools that flag applications before a human examiner opens the file. Every Kaleidoscope application is built to clear that screen from the outset.
Since August 2019, the USPTO has mandated that every trademark applicant whose permanent legal residence or principal place of business is outside the United States must be represented by a U.S.-licensed attorney. This is not a recommendation. It is a filing requirement.
An application submitted without qualified U.S. legal representation is rejected outright — fees unrefunded, priority date lost. Your clients already need a U.S. attorney of record. The only question is whether that attorney is the right one.
Online filing services are not U.S. attorneys. Platforms that offer trademark filing as a product do not satisfy this requirement. Applications filed this way are rejected with no recourse.
Your home-country attorney is not a U.S. attorney. Unless they hold a separate U.S. bar license, they cannot represent your client before the USPTO.
USPTO Rule — 37 C.F.R. § 2.11
"A foreign-domiciled applicant must be represented by an attorney who is an active member in good standing of the bar of the highest court of any U.S. state."

"Most trademark attorneys have filed applications and responded to rejections — but they've never been the one making the call. I held that job for 10 years."
Kay Dindayal · Founder, Kaleidoscope LawKaleidoscope charges flat fees billed directly to the end-client — no fee-splitting and no referral fees in either direction. A full pricing schedule, including Preferred Partner and Strategic Partner volume tiers for firms referring multiple matters annually, is available on request. USPTO government fees are confirmed separately and paid through the client.
This arrangement operates on professional goodwill and mutual practice development — not fee-splitting. This keeps the engagement clean under New York bar rules and your jurisdiction's professional conduct requirements. The value of the partnership is a reliable U.S. counterpart who reflects well on your firm.
When Kaleidoscope's clients need trademark protection in your jurisdiction, the firm refers them to partnering practices. This is an active practice — not a courtesy. The quality of Kaleidoscope's client base reflects the standard of work Kay brings to every engagement.
Comprehensive clearance search. Full written opinion with risk grading. Strategy briefing calibrated to result — peer briefing with referring counsel where risk is low; joint client + counsel briefing where risk is medium or higher, so material decisions are made by the end-client with direct access to U.S. counsel. Application preparation and filing. Non-substantive office action responses — included. Substantive office action defense available as a separate engagement, subject to merits assessment. Monitoring through to registration certificate. Renewal deadline tracking (renewal filings quoted separately).
Federal trademark database, state records, and common-law sources — conducted with professional search tools and analysed directly by Kay using her decade of USPTO examination experience. An analysis by the attorney who used to decide what constitutes a conflict.
A full written analysis of conflicts found, the risk level of each, recommended filing categories, and the strategy for the strongest possible path through U.S. review. Delivered in a format your firm can present directly to the client.
Drafted with the language and category construction that gives the application the widest defensible scope — engineered for the $350 USPTO filing tier where eligible. Filed by a firm whose founder spent a decade as the examiner.
Non-substantive office actions are resolved as part of the engagement at no additional fee. Substantive refusals — likelihood of confusion, descriptiveness, failure to function, and others — are handled as a separate engagement and accepted only on matters that meet Kaleidoscope's 65% likelihood-of-success threshold. Kay personally wrote hundreds of these refusals during her decade at the USPTO; that institutional experience is what makes selective representation possible.
Kaleidoscope tracks the application through to the registration certificate and notifies your firm at every key milestone. Renewal deadlines are monitored so nothing lapses without your firm being informed.
Each matter is documented in a direct engagement letter between Kaleidoscope Law and the end-client. With the client's written consent, routine status updates and prosecution communications route through your firm for operational efficiency, and your firm is copied on all material USPTO correspondence. The end-client retains direct access to Kaleidoscope at all times, and material decisions — substantive response strategy, abandonment, settlement of opposition — are made by the end-client and documented on the matter file. Kaleidoscope Law exercises independent professional judgment on all U.S. legal questions.

The mandatory representation requirement means the question was never whether your client needs U.S. counsel. It's whether the firm they work with reflects the standard of advice you provide. Kaleidoscope Law is the only U.S. trademark practice led by a former USPTO Examining Attorney — someone who spent a decade deciding which applications cleared, and which ones didn't.
