What is a Patent?
A patent is a legal right granted by a government authority that allows an inventor to exclusively make, use, sell, or license their invention for up to 20 years, provided they pay renewal fees.
It serves a dual purpose:
- They reward inventors with exclusivity, encouraging them to invest in innovation.
- They help society by disclosing technical knowledge, which others can build upon once the patent expires.
For example, imagine someone invents a solar-powered water purifier that can filter water more cheaply than existing methods. By patenting this invention, the inventor gains the exclusive right to manufacture and sell the purifier, thereby preventing competitors from copying it for 20 years. After that, the purifier design becomes free for public use.

Patent Filing Process
The filing process can feel overwhelming, but breaking it into logical steps makes it clearer:
Step 1: Patent Search and Prior Art Analysis
- Conduct a thorough search to check whether your invention already exists.
- Professional search agencies and patent attorneys can help identify similar patents to assess the uniqueness of your invention.
Step 2: Drafting the Patent Application
- Prepare a detailed specification, including technical drawings, claims, and a written description of the invention.
- Well-drafted claims are crucial because they define the exact scope of your protection.
Step 3: Filing the Application
- Submit your application to the national patent office (like the USPTO in the USA or IPO in India) or through the WIPO for international applications under the Patent Cooperation Treaty (PCT).
Step 4: Examination and Publication
- The offices verify that the application complies with formal rules and then review it in detail to determine if the invention qualifies.
- Applications are generally published after 18 months, even if the grant is pending.
Step 5: Responding to Objections
- Examiners may raise objections; you or your attorney must respond with clarifications or amendments to address these objections.
Step 6: Grant and Maintenance
- Once the examiner resolves any objections, the office grants and publishes the patent.
- Periodic renewal or maintenance fees are required to maintain the patent’s validity.
Real-World Examples of Patents
Here are some famous examples:
1. Apple iPhone
Apple’s multi-touch user interface patent transformed how people interact with smartphones, setting a new industry standard.
2. Pfizer’s Lipitor

5. Google’s PageRank Algorithm
Although now expired, this patent played a major role in Google’s search engine success and competitive advantage in the early 2000s.
Types of Patents
Here is a deeper dive into the different types:
1. Utility Patents
- These are the most common patents. They protect new and useful processes, machines, products, chemical compositions, or improvements to them.
- Examples include a new drug formulation, an improved engine, or a novel manufacturing process.
2. Design Patents
- Protect the unique visual qualities or ornamental design of a manufactured item rather than its technical function.
- For example, a design patent can protect the appearance of a smartphone or a piece of furniture.
- Generally, design patents in the United States have a term of 15 years.
3. Plant Patents
- Granted to those who discover or invent and asexually reproduce a new variety of plants.
- This protects cultivars, such as new rose varieties or disease-resistant fruits.
4. Provisional Patents
- It is not a full patent, but it serves as a temporary step, allowing inventors to secure a filing date while they continue working on their invention.
- You can use a provisional application for up to 12 months, after which you must file a full (non-provisional) application to continue the process.
- Helps reduce costs and provides time for market research or further R&D.
Patentability Requirements
To get a patent, an invention must satisfy these key conditions:
- Novelty: The inventor must create something new that no one has disclosed in any prior art anywhere in the world before the filing date. Even publication in a research journal can disqualify it.
- Non-obviousness (Inventive Step): The invention should not be obvious to a person having ordinary skill in the relevant field of technology. The improvement or innovation must be significant enough to be considered inventive.
- Industrial Applicability (Utility): The invention must have practical application and be capable of being made or used in industry, agriculture, or other sectors.
Benefits of Patents
Patents offer a wide range of benefits, making them a vital tool for individuals, startups, research institutions, and large corporations:
- Exclusive Rights: The patent holder can prevent others from manufacturing, selling, or using their invention without permission.
- Monetary Rewards: It can be licensed to third parties for royalties or even sold outright, creating additional revenue streams.
- Market Advantage: Blocking competitors from using your patented technology helps safeguard market share and foster brand loyalty.
- Increased Investment Appeal: Investors and venture capitalists prefer to fund businesses with protected intellectual property, as it reduces the risk of competitive threats.
- Encourages Further Innovation: Since patents allow creators to benefit financially, they incentivize continued R&D efforts.
- Public Disclosure: Publication of patents contributes to technological knowledge, enabling other inventors to build upon them after the patent expires.
International Patent Protection
Patents protect inventions only within the jurisdiction where the patent office grants them. If you require protection in multiple countries, you must file separately in each one.
The PCT streamlines this process by enabling inventors to file a single international application, valid across more than 150 member states, which buys time (up to 30 months) before entering national phases in each country.
Regional systems, such as the European Patent Office (EPO), enable inventors to apply once and obtain patents approved for multiple European countries, thereby making the process more cost-effective and easier to manage.
Patent Infringement and Enforcement
The owners can protect their rights by suing anyone who uses their invention without permission. This includes making, selling, importing, or offering the patented product or process without approval.
The enforcement generally involves:
- Cease-and-desist notices to stop infringement
- Litigation in civil courts for damages or royalties
- Injunctions to prevent further unauthorized use
- Customs measures to block infringing imports.
Patents vs. Trademarks vs. Copyrights
It is common to confuse different types of intellectual property. Here is a simple table to make the differences crystal clear:
| Aspect | Patents | Trademarks | Copyrights |
| What it protects | New inventions, processes, machines, compositions | Brand identifiers (words, logos, symbols) | Original creative works (literature, music, art, etc.) |
| Duration | 20 years from filing (usually) | Indefinite, renewable every 10 years | Author’s lifetime + 60/70 years (varies by country) |
| Registration | Mandatory registration with the office | Registration recommended, some protection automatic | Automatic upon creation, registration optional |
| Example | New drug formula, machine, or process | Nike swoosh logo, Coca-Cola bottle design | Novels, movies, songs, software code |
| Purpose | Encourage innovation by giving exclusivity | Distinguish goods/services in the marketplace | Protect the expression of ideas, promote creativity |
| Scope | Technical/industrial inventions | Branding elements | Literary and artistic expression |
