Who We Are

Devin Patent

Every Filing Is A Document Someone Will Later Read Against You.

Devin Patent is a trademark and patent attorneyship office based in Istanbul, acting for Turkish and international rights holders. Registered attorneys handle every stage of a right — searches, applications, oppositions, YİDK proceedings, renewals, recordals and portfolio administration before TÜRKPATENT, EUIPO, WIPO and the EPO.

What separates the office from most of the market is where its people come from. Our attorneys have legal training, and a specification, a claim set or an opposition brief is drafted the way a document is drafted when you expect it to be tested later — against the statute, against examination practice, and against the case law that sits behind both.

That shows up in ordinary decisions. Which classes to file and how to word them. How broadly to draft a claim before it stops being defensible. Whether to build evidence of use in the first year rather than assemble it under deadline pressure in the fifth. Whether a consent letter is worth asking for, and what it should say.

Portfolios are run on a single calendar. Opposition windows, renewal dates and annuity deadlines are docketed centrally, audits identify dormant rights and gaps in class coverage, and clients receive scheduled status reporting rather than an invoice and a certificate.

Court proceedings, compensation claims, criminal complaints, contract drafting and advisory work are not carried out here. They are handled by our law firm, Devin Law & IP, and a file moves between the two offices without losing its history.

Why Choose Us

Attorneys With Legal Training

Every file is handled by registered trademark attorneys who also hold a legal education; patent files are prepared together with patent attorneys, and the European route with European patent attorneys. Examination decisions are read against the statute and the case law behind them rather than accepted as administrative outcomes.

Searched Before It Is Filed

Nothing goes to the register before it has been searched. Availability, identity and prior art searches are run first, and where the result is negative we say so plainly instead of filing an application that will not survive examination.

One Calendar, Nothing Missed

Opposition windows, renewal dates, annuities and national phase deadlines are docketed centrally with layered reminders. Deadline discipline is the single most valuable thing an attorneyship office can offer, and we treat it that way.

Filed Abroad Under One Roof

Madrid, PCT, the European patent route, the Hague System, EUIPO and direct national filings are coordinated from Istanbul through a vetted associate network, so strategy, timing and budget stay consistent across every jurisdiction.

A Clear Route To The Courtroom

When a matter has to leave the register and go to court, it moves to Devin Law & IP with the full prosecution history behind it. Nothing is rebuilt from scratch and nothing is lost in the handover.
