Introduction to Patent

A patent is a form of legal protection granted to inventors by the government for a certain period of time. It gives the inventor the exclusive right to prevent others from making, using, selling, or importing an invention without permission. In return for this protection, the inventor must publicly disclose the details of the invention, so that others can learn from it once the patent expires.

Patents can be granted for a variety of different types of inventions, including products, processes, and machines. They can also be granted for new and useful improvements to existing products, processes or machines. In order to be eligible for a patent, an invention must be novel, non-obvious, and useful.

Patent rights can be sold, assigned or licensed. Patents often play important role in a company’s business model and its valued assets. They can also be used as a way to raise capital, by licensing or selling the rights to the invention to others.

Obtaining a patent can be a time-consuming and costly process, and it requires the services of a patent attorney or agent. The patent office in the country where patent is sought to be granted will examine the application and will decide whether to grant a patent or not. In most countries, the granted patent is valid for 20 years from the date of filing.

Definition of patent

A patent is a legal document that grants an inventor exclusive rights to prevent others from making, using, selling, or importing an invention for a certain period of time, typically 20 years from the date of application. In return for this protection, the inventor must publicly disclose the details of the invention, so that others can learn from it once the patent expires. This means that anyone can use the invention after the patent has expired, but during the time the patent is in force no one else can use the same invention without the permission of the patent holder.

To be eligible for a patent, an invention must meet certain criteria such as being new, non-obvious and useful. This means that the invention must not have been previously disclosed or made available to the public before the patent application, it should not be an obvious development from the current technology, and it should have some kind of practical application or utility. Patents are generally issued for novel products, processes, and machines and also for new and useful improvements to existing products, processes or machines.

A Patent right is

A patent right is the exclusive legal right granted to an inventor or patent holder by a government to prevent others from making, using, selling, or importing an invention without permission for a certain period of time. This legal right is granted to inventors as a way to encourage and promote innovation and technological development.

The patent holder has the right to exclude others from making, using, selling, offering for sale, or importing the patented invention for the life of the patent. The patent holder can also license or assign the patent to others. However, any person can challenge the validity of the patent in front of a court if he believes that the patent is not valid or not truly novel and non-obvious.

The holder of a patent can use it to prevent other people from commercially exploiting their invention, and they can also use it to generate revenue through licensing the patent or selling the rights to the invention to others. Patent protection provides an incentive for inventors to invest time and money in the development of new and useful products, processes and machines, as it gives them a chance to recoup their investments and profits by exclusive commercial exploitation of their invention.

Patent an idea

In order to patent an idea, the idea must first be reduced to a tangible form, such as a working prototype or a detailed description of how the invention works. The next step is to conduct a patent search to ensure that your idea is novel and non-obvious, that is that it is not already patented or published by others. This will help you to understand if your idea is already patented and if there is similar ideas that can be an obstacle for getting a patent.

After the patent search is completed, you will need to draft a patent application that includes a detailed description of the invention, how it works, and how it is novel and non-obvious. The application also needs to include any drawings or diagrams that will help explain the invention.

The patent application is then filed with the appropriate government agency, typically the national patent office. The patent office will review the application and conduct its own search to ensure that the invention is eligible for a patent. The process of obtaining a patent can take several years and requires the services of a patent attorney or agent.

It is important to note that getting a patent is not guaranteed even if the idea is novel and non-obvious, as the patent office may have other reasons such as claiming that the invention is not useful to reject the patent application.

Keep in mind that the patent process can be time-consuming and expensive, so it is important to carefully evaluate whether obtaining a patent is worth the cost and effort before beginning the process. It may also be beneficial to consult with a patent attorney or agent to help navigate the process and determine the best strategy for your invention.

Scope of Patent

In India, patents are granted for inventions that are new, involve an inventive step, and are capable of industrial application. In order to be eligible for a patent, an invention must not fall under any of the categories of the excluded subject matter specified in the Indian Patents Act, such as mathematical or business methods, plant varieties, and essentially biological processes for the production of plants. The term of a patent in India is 20 years from the date of filing, subject to the payment of maintenance fees. The Indian patent system is governed by the Indian Patents Act, of 1970 and the Patents Rules, of 2003.

Patentability Criteria

Patentability criteria are the legal requirements that an invention must meet in order to be eligible for a patent. These criteria vary depending on the jurisdiction, but generally include:

Novelty

Novelty is a requirement for patentability and it refers to the aspect of an invention that must be new and not previously disclosed to the public. For an invention to be considered novel, it must not have been anticipated by a single prior art reference or by a combination of prior art references.

Prior art refers to all information that has been made available to the public in any form before the date of filing or priority date of a patent application. Prior art can include, for example, patents, publications, and products that are already available on the market.

The scope of the prior art can vary depending on the jurisdiction, some countries may include international references, and some may not, so it’s important to check the law in the specific jurisdiction where you are filing a patent application.

If a single prior art reference or a combination of prior art references disclose all the essential features of the invention claimed in a patent application, the invention is not considered to be novel and therefore, it is not eligible for a patent.

Novelty is determined at the time of filing the patent application or priority date of patent application, and it’s important to keep in mind that an invention can be made public before a patent application is filed, it can still be considered novel if it was not available to the public before the application was filed or priority date.

It’s always best to consult with a patent attorney who can help you determine whether your invention is novel and if it meets the requirement of novelty for patentability.

Non-obviousness

Non-obviousness, also known as inventiveness or inventive step, is a requirement for patentability, and refers to the aspect of an invention that must not be obvious to a person having ordinary skill in the relevant field of technology.

In order to be considered non-obvious, an invention must not have been obvious to a person of ordinary skill in the field of the invention at the time of the invention. This means that an invention is not considered non-obvious if it would have been obvious to a person of ordinary skill in the field of the invention at the time of the invention, using the prior art available at the time of the invention.

The determination of non-obviousness is generally made by comparing the claimed invention to the prior art, to determine if the invention would have been obvious to a person of ordinary skill in the field of the invention at the time of the invention.

When assessing the non-obviousness, the examiners and courts consider various factors such as similarity of subject matter, the level of ordinary skill in the field, the secondary considerations, etc.

It’s important to note that it is not always straightforward to determine whether an invention is non-obvious and the determination of non-obviousness can be complex and often depends on the specific facts of the case. Therefore, it’s always best to consult with a patent attorney who can help you determine whether your invention meets the requirement of non-obviousness for patentability.

Industrial Applicability

Industrial applicability, also known as utility, is a requirement for patentability and refers to the aspect of an invention that must have some useful or practical application. This means that the invention must be capable of being made or used in industry.

The industrial applicability requirement is met when the invention can be made or used to produce a useful result or achieve a useful purpose. The requirement is met if the invention can be applied in any field, including agriculture, medicine, industry, or services.

When assessing the industrial applicability of the invention, the examination authorities and the courts consider various factors such as sufficiency of disclosure, operability, the possibility of practical application, etc. The disclosure in the patent application must be sufficient to demonstrate the operability of the invention, to establish the possibility of the practical application of the invention and enable the person skilled in the art to practice the invention.

It’s important to note that an invention does not need to be commercially successful or profitable to meet the industrial applicability requirement.

It’s always best to consult with a patent attorney who can help you determine whether your invention meets the requirement of industrial applicability for patentability.

In addition to these criteria, some jurisdictions may have additional requirements for patentability such as, but not limited to:

  • Disclosure: The invention must be fully and clearly disclosed in the patent application so that a person skilled in the relevant field of technology can understand and replicate it.
  • Exclusion: Certain types of inventions may be specifically excluded by law from being patented, such as laws of nature, natural phenomena, abstract ideas, literary, dramatic, musical or artistic works, or surgical and therapeutic methods.

It’s important to note that the interpretation and application of these criteria can vary depending on the specific laws of the country where you seek a patent and interpretation of courts. Therefore, it’s always best to consult with a patent attorney to understand the specific requirements for patentability in the jurisdiction you are filing your patent application.

Types of Patents in India

There are several types of patents that can be granted by the government to inventors, each with its own specific requirements and scope of protection. The most common types of patents include:

Utility Patents

 These patents are granted for new and useful processes, machines, articles of manufacture, or compositions of matter, or new and useful improvements thereof. Utility patents are the most common type of patent and provide protection for the functional aspects of an invention.

Utility patents are a form of legal protection granted by the government to inventors for a certain period of time, typically 20 years from the date of application. Utility patents are granted for new and useful processes, machines, articles of manufacture, or compositions of matter, or new and useful improvements thereof. They are the most common type of patent and provide protection for the functional aspects of an invention.

Obtaining a utility patent requires the inventor to draft and file a patent application with the appropriate government agency, typically the national patent office. The patent application must include a detailed description of the invention, how it works, and how it is novel and non-obvious. The application also needs to include any drawings or diagrams that will help explain the invention. Once the application is filed, the patent office will review it and conduct its own search to ensure that the invention is eligible for a patent.

Before filing a utility patent, it’s important to conduct a patent search to ensure that the invention is novel and non-obvious, and it is not already patented or published by others. This will help the inventor to understand if their idea is already patented and if there is similar ideas that can be an obstacle to getting a patent.

To be eligible for a utility patent, an invention must meet certain criteria such as being new, non-obvious and useful. This means that the invention must not have been previously disclosed or made available to the public before the patent application, it should not be an obvious development from the current technology, and it should have some kind of practical application or utility.

Once a utility patent is granted, the patent holder has the exclusive legal right to prevent others from making, using, selling, or importing the invention without permission for the life of the patent. The patent holder can also license or assign the patent to others.

It’s important to note that obtaining a utility patent can be a time-consuming and costly process, and it requires the services of a patent attorney or agent. Also, the patent office may reject the patent application if the invention is not useful, even if it is novel and non-obvious.

In conclusion, utility patents are an important tool for inventors to protect their ideas and inventions. They provide inventors with a way to secure exclusive rights to their inventions and to prevent others from making, using, or selling it without permission. The process of obtaining a utility patent can be complex, but it is worth the time and effort if you have a valuable invention. Inventors should consider consulting with a patent attorney or agent to help navigate the process and determine the best strategy for their invention.

Design Patents

Design patents are a type of legal protection granted by the government to inventors for new, original, and ornamental designs for an article of manufacture. They provide inventors with the exclusive right to prevent others from making, using, selling or importing an invention that is identical or substantially similar to the patented design for a certain period of time, typically 15 years from the date of grant in the United States.

Design patents are different from utility patents, which protect the functional aspects of an invention, such as the way it works or the materials it is made from. Instead, design patents protect the aesthetic or ornamental features of an invention, such as its shape, colour, texture, or pattern. This means that design patents can protect a wide range of products, from clothing and jewellery to furniture and consumer goods.

Obtaining a design patent is a fairly simple process, and it is not as expensive as utility patents. The process usually starts with a design patent application that includes several drawings or photographs of the invention, which will be used to determine whether the design is novel and non-obvious. The drawings should be detailed enough to show the ornamental features of the invention, as well as the perspective view. In some countries, like US, 3D models can also be submitted as a part of the application.

Once the application is filed, it will be reviewed by a patent examiner to ensure that the design meets the requirements for a design patent. The examiner will compare the design to existing designs to ensure that it is new and non-obvious.

If the design is approved, the inventor will be granted a design patent. After that, the patent holder has the exclusive right to prevent others from making, using, selling, or importing articles of manufacture that are identical or substantially similar to the patented design for the life of the patent.

Design patents can play an important role in protecting a company’s valuable assets and intellectual property. They can be an important way to prevent competitors from copying a company’s products and designs, and they can also be used to generate revenue through licensing or selling the rights to the design.

However, it’s worth noting that design patents do not protect the functionality of the invention, they only protect the appearance, so it is possible to have an invention with similar functionality but a different appearance that would not infringe the patent.

In summary, design patents can provide valuable protection for inventors and companies who have developed new and original ornamental designs for an article of manufacture. They can help to prevent competitors from copying designs and can generate revenue through licensing or selling the rights to the design.

Plant Patents

Plant patents are a unique form of intellectual property protection that is specifically designed to protect new and distinct plant varieties. These patents are granted by the government to individuals or organizations who have invented or discovered and asexually reproduced a new plant variety. Asexually reproduced plants are those that are reproduced by methods such as rooting cuttings, grafting, or budding, as opposed to sexually reproducing plants that are reproduced through seed.

One of the main requirements for a plant patent is that the plant must be new and distinct. This means that the plant must not have been sold or distributed to others more than one year prior to the date of filing the patent application, and it must be distinguishable from all other known varieties of the same kind. The plant must also have been asexually reproduced and be stable, meaning it reproduces true to type.

In order to obtain a plant patent, the inventor must file a patent application with the United States Patent and Trademark Office (USPTO). The application must include a detailed description of the plant, including information on its botanical classification, its characteristics and its method of asexual reproduction. It should also include photographs or drawings of the plant, as well as any other information that may be required by the USPTO.

The USPTO will review the application and conduct its own examination to determine whether the plant is new and distinct and whether it meets the other requirements for a plant patent. If the patent is granted, the inventor will have the exclusive right to prevent others from reproducing, selling, or importing the plant variety for a period of 20 years from the date of the grant. This means that no one can use that plant variety without the permission of the patent holder.

Plant patents have been used to protect a wide variety of plant varieties, including flowers, fruits, vegetables, and ornamental plants. They have been particularly useful for small-scale plant breeders and nurseries, as well as for larger organizations such as universities and agricultural companies.

It’s important to note that the patent system for plants may vary from country to country, for example in EU member states, plant patents may not be available, However, there is an alternative option, it’s the Plant variety rights, that protect new varieties of plants that are obtained by selective breeding, or mutation and that are uniform, stable, and reproducible.

In any case, Plant patents and Plant variety rights, provide an important form of protection for plant breeders and help to encourage the development of new and improved plant varieties. It ensures that the efforts and investments made by the breeders are rewarded and incentivizes the continuous development of new plant varieties that can have a positive impact on the agriculture and horticulture industries.

Provisional Patents

These are temporary patents that are valid for 12 months, during which time the inventor can file a non-provisional patent application. Provisional patents are useful for inventors who need to establish an early effective filing date for their inventions.

PCT International Patent

The Patent Cooperation Treaty (PCT) is an international patent law treaty that was implemented in 1978 by the World Intellectual Property Organization (WIPO). The PCT makes it possible to seek patent protection in multiple countries by filing a single patent application, known as an international application.

The main advantage of the PCT system is that it allows applicants to file a single patent application that can be used to seek protection in multiple countries, rather than having to file separate applications in each country where protection is sought. This can save time and money for the applicant, and it also allows for a centralized examination of the patent application.

When an international application is filed, it is examined by a national patent office or an international search authority (ISA) to ensure that it meets the basic requirements for patentability, such as novelty, non-obviousness, and usefulness. This examination process is known as the international search. After the international search is completed, the applicant can request an international preliminary examination, which is conducted by an international preliminary examination authority (IPEA), to determine whether the invention is likely to be granted a patent in the countries where protection is sought.

After the international search and international preliminary examination, the applicant can enter the national phase, which is the process of seeking protection in individual countries. The applicant must file a separate application for each country in which protection is sought and the application will be examined by the national patent office in accordance with the laws of that country.

The PCT system allows for a time period of 30 months from the earliest priority date of the international application for the applicants to enter into the national phase. This gives applicants enough time to consider which countries they wish to seek protection in and to make any necessary changes to their application before it is examined by the national patent office.

The PCT system provides a streamlined and efficient way for inventors and businesses to seek patent protection in multiple countries. It also enables a more centralized examination process, which can lead to a more consistent application of patent law across different countries.

It is important to note that while the PCT system simplifies the process of seeking patent protection in multiple countries, it does not grant a patent directly. The applicant will still have to go through the examination process in each country in which they seek protection. Additionally, not all countries participate in the PCT system, so it’s essential to research and consult with a patent attorney to understand if and how your invention can be protected under the PCT.

It’s important to note that the requirements and process for obtaining each type of patent may vary from country to country and you should consult the national patent office for more information on the specific requirements for each type of patent.

What can be patented?

In general, a patent is a legal monopoly granted to an inventor or assignee for a certain period of time, in exchange for full public disclosure of the invention when the patent is granted. During this time, no one else can make, use, or sell the invention without the patent holder’s permission.

Some examples of things that can be patented include:

  • A new machine or device
  • A process or method of making or using a machine or device
  • A composition of matter (for example, a new chemical compound or a new plant variety)
  • A novel design for an object
  • An improved version of an existing product or process

However, not all types of inventions can be patented. Some examples of things that are typically not eligible for patent protection include:

  • Laws of nature
  • Natural phenomena
  • Abstract ideas
  • Literary, dramatic, musical, or artistic works
  • Performing methods or playing games

The rules for patentability may vary from country to country, so the scope of patent protection will depend on the specific laws of the country where you seek a patent.

What cannot be patented?

Not all types of inventions are eligible for patent protection. Some examples of things that are typically not eligible for patent protection include:

  • Laws of nature: These are principles that describe how the world works, such as gravity, and cannot be claimed as an invention.
  • Natural phenomena: This includes observations or discoveries of natural phenomena, such as the circulation of blood or solar eclipses.
  • Abstract ideas: This includes concepts, methods, or mathematical algorithms that are not applied to any specific process or machine.
  • Literary, dramatic, musical, or artistic works: These are typically protected by copyright laws, not patent laws.
  • Performing methods or playing games: These cannot be patented as process
  • Plant varieties: Plant varieties that are obtained by essentially biological processes for the production of plants cannot be patented.

It’s also important to note that in some countries, including India, certain categories of subject matter are specifically excluded from patent protection by statute. As, Traditional Knowledge, discoveries of new forms of existing known substances, mere admixture resulting only in the aggregation of the properties of the components thereof or diagnostic, therapeutic and surgical methods for the treatment of humans or animals cannot be patented.

It’s always best to consult with a patent attorney to determine whether your invention is eligible for patent protection, as the rules can vary depending on the jurisdiction.

Product Patent and Process Patent

A product patent is a type of patent that is granted for a new, useful, and non-obvious invention that can take the form of a tangible product or a composition of matter. Examples of things that can be protected by a product patent include:

  • A new chemical compound or a new drug
  • A new machine or device
  • A new type of plant or genetically modified organism
  • A new design for an object
  • A new type of material such as a new alloy or a new type of composite

On the other hand, a process patent is a type of patent that is granted for a new and non-obvious process or method of making a product or using a product. Examples of things that can be protected by a process patent include:

  • A new method of manufacturing a product
  • A new way of using a product
  • A new industrial process
  • A new software-implemented method

Both product and process patents provide the patent holder with the exclusive right to make, use, and sell the invention, usually for a period of 20 years from the date of filing (in India) and subject to maintenance fees. However, the scope of protection provided by a product patent and a process patent can be different. A product patent may give the patent holder exclusive rights over the manufacture, use and sale of the product, whereas a process patent may only give the patent holder exclusive rights over the use of the process, which might not prevent others from making the same product by using a different process.

Law Governing patents in India

In India, the laws covering patents are governed by the Indian Patents Act, of 1970 and the Patents Rules, of 2003. The Indian Patents Act, of 1970 defines the scope and extent of patent protection in India and lays out the procedures for obtaining and enforcing patents.

The Act specifies the types of subject matter that are eligible for patent protection, such as inventions related to a product or process in any field of technology, such as pharmaceuticals, biotechnology, software, electronics, and mechanical engineering, Improvements to existing inventions, new uses of a known product or process and a new process for making a known product.

The Act also lays out the criteria for patentability, which include that an invention must be novel, involve an inventive step, and be capable of industrial application. Additionally, it must not fall under any of the categories of the excluded subject matter specified in the Indian Patents Act, such as mathematical or business methods, plant varieties, and essentially biological processes for the production of plants.

The Patents Rules, 2003 lays out the procedural requirements for obtaining a patent in India, such as the filing and examination of patent applications, the grant and maintenance of patents, and the enforcement of patent rights. It also lays out the fees associated with various stages of the patent process such as filing, examination, grant, and maintenance.

India also has a system for post-grant opposition, that allows for a third party to file a request for the opposition of a granted patent within a year of the grant or six months from the date of publication of the grant of the patent, whichever is later.

It’s always best to consult with a patent attorney who is well-versed in Indian patent law to understand the specific requirements and procedures for obtaining a patent in India.

Conclusion

In conclusion, obtaining a patent for an invention requires meeting certain legal requirements set by the jurisdiction in which the patent is sought. These requirements typically include novelty, non-obviousness, and industrial applicability, among others.

Novelty means that the invention must be new and not previously disclosed to the public. The non-obviousness requirement means that the invention must not be obvious to a person having ordinary skills in the relevant field of technology. The industrial applicability requirement means that the invention must have some useful or practical application and be capable of being made or used in an industry.

Meeting these criteria may be complex and depends on the specific facts of the case. It’s always best to consult with a patent attorney who can help you determine whether your invention meets the requirements for patentability. They can also guide you through the process of filing a patent application, and provide legal advice and representation in case of patent disputes.
