Difference Between Patents and Trademarks
Difference Between Patents and Trademarks
1. Definition
Patent:
A patent grants the inventor exclusive rights over a new invention or process for a limited period, typically 20 years. It protects the functional and technical aspects of inventions.
Trademark:
A trademark is a sign, symbol, word, or logo used to identify and distinguish the goods or services of one business from those of others. It protects brand identity and goodwill.
2. Subject Matter
| Patent | Trademark |
|---|---|
| Inventions, processes, machines, products, compositions of matter | Logos, brand names, slogans, symbols, sounds, colors used in trade |
3. Purpose
Patent:
To encourage innovation by giving the inventor exclusive rights to exploit their invention.
Trademark:
To protect consumers and businesses by preventing confusion over the origin of goods or services.
4. Duration
Patent:
Protection typically lasts 20 years from the date of filing, after which the invention enters the public domain.
Trademark:
Protection can be indefinite as long as the mark is in use and renewed periodically (usually every 10 years).
5. Rights Granted
Patent:
Exclusive right to make, use, sell, or license the invention.
Trademark:
Exclusive right to use the mark in commerce and prevent others from using confusingly similar marks.
6. Requirement for Registration
Patent:
Registration is usually necessary to obtain exclusive rights (except in some countries where certain inventions may have protection without registration).
Trademark:
Registration provides stronger protection but in some jurisdictions, rights can be claimed through use.
7. Infringement and Enforcement
Patent:
Unauthorized manufacture, use, or sale of the patented invention is infringement.
Trademark:
Unauthorized use of the trademark or a confusingly similar mark on related goods/services is infringement.
Case Law Examples
Patent Case: Bajaj Auto Ltd. v. TVS Motor Company Ltd.
Issue: Bajaj claimed that TVS infringed its patented motorcycle technology.

Trademark Case: Cadbury India Ltd. v. Neeraj Food Products
Issue: Cadbury alleged that Neeraj was using a mark similar to its famous "Dairy Milk" trademark.
Held: The court restrained Neeraj from using the confusingly similar mark to prevent consumer deception.
Significance: Emphasizes trademarks’ role in protecting brand identity and consumer interests.
