Protecting a trade mark
Read about registration, earlier rights and the limits of a registered mark.
In plain English · by srilaws · not legal advice· Law as at 12 Nov 2003

The short answer
The Act distinguishes trade marks for goods, service marks for services and trade names identifying an enterprise. The exclusive right to a mark under this Part is acquired by registration, subject to the later provisions. Start by identifying the sign and the goods or services it is meant to distinguish; this guide is not a clearance opinion on a proposed brand.

Check both kinds of objection
The Act lists objective grounds for refusing a mark, including lack of distinctiveness and misleading signs. It also protects earlier third-party interests, including specified earlier registered or used marks and trade names. A name being available for a company does not answer all of these trade-mark questions. Read both sets of grounds before assuming a sign is registrable.
Preparing an application
The application provision calls for the prescribed form, applicant details, a representation of the mark and a clear list of the relevant goods or services and classes. Applications made through an agent require a power of attorney. The cited publication gives the legal requirements; check current forms, fees and submission procedures separately.
Examination and opposition
The Act provides for examination against the refusal grounds and written reasons for refusal. It also provides for publication and an opportunity for opposition, with procedures for the applicant’s response and a decision. Filing an application is therefore distinct from obtaining registration. Read notices carefully because the statutory process contains time limits.
Rights have boundaries
A registered owner has rights to use the mark, transfer the registration and license it, subject to the Part’s other provisions. The Act restricts certain misleading uses by third parties. It also contains limits on the owner’s rights, including specified identifying uses and dealings in unchanged goods lawfully put into circulation in Sri Lanka under the mark. Registration has a duration. The Act also provides a renewal procedure. Read the scope and renewal provisions before assuming protection is unlimited or permanent.

Responding to an examination notice
The cited text allows written submissions against a notified refusal within one month from the notification. Publication then creates a distinct opportunity for opposition: a person opposing registration has three months from publication to give the prescribed notice, grounds and supporting evidence. If opposition is received, the applicant is asked for written observations and evidence within three months. The section also permits reasonable extensions of prescribed periods. Keep examination, publication and opposition notices separate; they concern different stages and should not be treated as a single filing deadline.
Keep renewal separate from registration
Registration may be renewed for consecutive periods of ten years on payment of the prescribed fee. The renewal fee is payable during the twelve months before expiry, with a six-month grace period after expiry subject to the prescribed surcharge. Renewal does not involve a further examination of the mark or opposition by another person. The Director-General removes the mark from the register if the fee is not paid within the applicable period. Record the registration and renewal documents together, and check current fee arrangements before acting on this as-enacted timetable.
