Patent & Utility Model Filing

A patent grants exclusivity over an invention for a limited period. In exchange, the invention is disclosed to the public: the system rests on a bargain — tell us how it works and you get protection. A patent application is therefore not a form-filling exercise but a drafting exercise, and the quality of that text determines the scope of the right.

The most common mistake is to focus on the invention and treat the claims as an afterthought. What is protected is not your invention but what the claims describe. Claims drafted too narrowly let a competitor step outside them with a trivial change; claims drafted too broadly read onto the prior art and are refused, or revoked later.

Patent or utility model?

Turkish law offers two forms of protection, and the choice follows the nature of the invention, the product’s life cycle and the budget:

• Patent — requires novelty, inventive step and industrial applicability. Protection runs twenty years from the filing date. The file passes through search and examination: slower, but the resulting right is stronger.
• Utility model — no inventive step is required; novelty and industrial applicability suffice. Protection runs ten years. Processes and chemical substances cannot be protected this way. Where the product cycle is short, the development step modest and speed critical, this is the right instrument.

A concrete comparison: patent or utility model?

Before filing: why novelty is so fragile

An invention must be new worldwide at the filing date, and "worldwide" is read broadly: a paper in a foreign language, a trade-fair stand, a video, even a product page on your own website can destroy novelty.

The commonest and costliest error is disclosing before filing — your own disclosure counts. Before exhibiting, pitching to investors or announcing a product, either file first or put a confidentiality agreement in place. For pre-filing screening: patent search.

From filing to grant

1. Analysis and draft specification. The technical problem, the solution and its difference from the prior art are put in writing. Drawings, worked examples and alternative embodiments are built in at this stage — they cannot be added later.
2. Claim drafting. Independent claims set the outer boundary; dependent claims form fallback positions. A good claim set leaves another line of defence behind each one that falls.
3. Filing and priority. The filing date anchors both the novelty assessment and any foreign filings: applications made abroad within twelve months can claim it.
4. Search report. A search is requested within the prescribed period and the Office reports the closest prior art. This is where the file’s real strength first becomes visible.
5. Publication. The application publishes eighteen months from the priority date and is opened to third-party observations. From that point the invention is public.
6. Examination. On request, the Office assesses novelty and inventive step on the merits. Observations are filed in response and, where needed, claims are narrowed to carry the file to grant.
7. Grant and annuities. After grant, protection is maintained by annual fees. Non-payment causes the right to lapse; see patent annuity fees.

Claim drafting: the real boundary of the right

In a patent dispute the court looks first at the claims. The description serves to interpret them; the claims define the scope. Two risks are therefore managed at once:

• Too narrow — a competitor makes a small change that falls outside the claim and is legally in the clear.
• Too broad — the claim reads onto the prior art and is refused during examination, or falls in later revocation proceedings.

The workable approach captures the core of the invention in as broad an independent claim as the art allows, with progressively narrower dependent claims beneath it, so that losing one claim does not lose the file.

Ownership and employee inventions

Where an invention is made by an employee in the course of their duties, rights may pass to the employer — but not automatically and not without compensation. Notification, claim and remuneration steps must be handled properly. A mishandled employee invention leaves ownership contestable years later. See employee inventions.

Protection abroad

Patents are territorial. Foreign filings must be made within the twelve-month priority period. The options are national filings, a European patent under the EPC, and the PCT route, which keeps all options open for up to thirty months. Comparison: international patents and the PCT.

Commercial and tax value

A patent is not only defensive. It can be licensed, pledged, and counted in a valuation, and it may bring earnings within the industrial property tax exemption. In R&D-intensive companies the patent portfolio is among the most closely examined items in a funding round; see the startup IP checklist.

Deadlines with no second chance

Unlike a trademark file, a patent file is deadline management from beginning to end. Skip any link in the chain below and the application either lapses or has its scope permanently narrowed:

• Search request — if not made within the statutory period, the application is deemed withdrawn.
• Examination request — due within the period following notification of the search report.
• Responses to office communications — each carries its own term; leaving one unanswered loses the file.
• Priority period — twelve months from first filing for foreign applications. It cannot be extended, and missing it destroys novelty abroad.
• Annuities — payable each year; once the grace period also passes, the right lapses irrecoverably.

Tracking that whole calendar from one place matters as much as the technical quality of the file. A significant share of patents lost in practice are lost not to refusal but to a missed date.

Inventor and proprietor are not the same person

An application involves two distinct capacities: the inventor who actually made the invention, and the person or company holding the right. Being named as inventor is a personal right and cannot be transferred; ownership can be. Where several inventors contributed, the shares of contribution and how ownership is divided should be recorded in writing before filing.

Neglecting this distinction turns into an ownership dispute years later, particularly in university collaborations, consultant-run projects and companies whose shareholding has changed. The more commercial value the patent acquires, the sharper the dispute.

Frequently asked questions

Can I patent an idea?

Ideas are not patentable. What is patentable is a concrete, applicable technical teaching that solves a technical problem. Business methods, mathematical methods and purely aesthetic creations are excluded as such. Whether software is patentable turns on whether it produces a technical effect.

Can I describe my invention before filing?

Not without a confidentiality agreement. Any public disclosure destroys novelty, including your own. Investor meetings and trade fairs are where this is most often lost.

How long does it take?

A utility model typically reaches grant in one to two years; a patent, including search and examination, in three to five. Because protection runs from the filing date, the wait costs you nothing in scope.

I have a patent — can anyone still copy me?

A patent is not a self-executing shield. Detecting infringement and taking action is the proprietor’s job; the Office does not police the market on your behalf.
