What is Patents:

A patent is grant of exclusive rights for an invention to make, use and sell the invention for a limited period of 20 years. The patent grant excludes others from making, using, or selling the invention. Patent protection does not start until the actual grant of a patent.

Patentable invention:

In order to be patentable an invention should have the following characteristics:

  • The invention should be process or product
  • The invention should be novel or new
  • It involves an inventive step
  • It is capable of industrial application

There is some sort of incentives for filling the patent application;

That cannot be patented as follow;

  1. Discovery, scientific theory, law of nature or mathematical method.
  2. Literary, dramatic, musical or artistic work or any other creation of purely aesthetic character whatsoever.
  3. Scheme, rule or method for performing a mental act, playing a game or doing business.
  4. The presentation of information, computer software.
  5. Exist in nature or isolated form.

Patent applications are examined under the Patents Ordinance, 2000 and Rules, 2003 there under for both technical and legal merits.


Registration of Patent:

Patent applications can be applied in the following manners:

  • An ordinary patent application with “provisional or complete specification”, which is dated as of the official date of the application for the patent.
  • A convention patent application claiming “right of priority”, which is dated as of the official date of the corresponding application for patent first made in a country which is the member of WTO (World Trade Organization).
  • Application for a patent of addition, for improvement or modification of an invention for which a patent has already been applied for or granted.

File First and Publish Later:

Publish later another important aspect when you posses an invention, is that you do not publish the invention in any way before filing the patent application. A patent can only be granted for an invention that has not yet been disclosed to the public, neither in writing nor orally. The right way is to first file application and then publish.

Steps for filing Patent Application:

  1. Prepare a Patent specification.
  • Draft High-quality writing which clear the terms will be bound.
  • Begin with title and at the end signed by the applicant.
  • Print on one side paper.
  • A4 size paper with minimum margins 2cm from top and bottom, 2.5cm from left side and 2cm from right side.

Please draft your complete-patent specification with following contents:

  1. Title of invention: Title of the invention sufficiently indicates the subject matter of the invention. It is best to avoid being overly narrow or broad in the invention’s title.
  2. Abstract: It includes all the important technical aspects of your invention. Abstract shall commence on a new sheet. The abstract 6 normally consists of not more than 2 pages. Abstract should mention those technical features of invention which are disclosed in detailed description part of the invention. It is advisable after writing abstract check all this disclosed in description part of the specification.
  3. Field of the invention: what area does the invention relate to? For example, for a new accessory for a motor car you may write “this invention relates to motor cars, more specifically an accessory for a motor car”.
  4. Background of the invention: why is the invention necessary or useful, and what has it developed out of? Continuing with the motor car accessory example, it may be that your accessory is an improvement on a previously existing accessory. Here you can discuss why the improvement is needed. It is important to discuss some ‘prior art’ here – patents that have already been filed by someone else relating to your idea. The background part may conclude with a short, crisp statement about the shortcomings of the prior art but this must be written in a manner that does not disclose the solution to be described later in the application. It should instead be written in a manner that makes the typical reader think: How anyone could ever solve this problem! It is advised don’t spend too much time preparing the background. A good rule of thumb is no more than a maximum of two pages and/or no more than 10 percent of the total content of the application. To find relevant prior art it is advised to perform a patent search in patent databases and non Patent literature.
  5. Detailed Description: How exactly does your invention work? Here you should describe in detail the exact components, systems, 7 methods and so on that make your invention work so that someone else skilled in the area would be able to reproduce it using your instructions. In drafting the detailed description part, avoid using phrases such as “the invention is…” instead of it use phrases like “in an embodiment of the invention.” This will ensure that patent claims receive the broadest interpretation possible. This part of the specification is generally presumed to disclose “an embodiment” of the invention rather than the invention itself. Please note that an embodiment by definition is a manner in which an invention can be made, used, practiced or expressed.
  6. Claims: precise legal statements in the form of single sentence that define the scope of your invention. Claims shall commence on a new sheet. The Patent application must end with one or more claims, at least one independent claim and other dependent claims. Usually begin with “I or We claim,” and should be sequentially numbered and be presented in order from broadest to narrowest. It is advisable that one of the first things to do is to prepare the claims for the invention. If the claims are prepared before drafting the other parts of specification you will know better which terms need to be described in the specification. Preamble or opening statement of the claim(s) must indicate whether a process or product feature of invention is claimed. Example I claim 1. A device, comprising: a pencil; and a light attached to the pencil. 2. The device as claimed in claim 1 wherein the light is detachably attached to the pencil. 3. The device as claimed in claim 2 wherein the pencil is made of wood. 8
  7. Drawings: what does your invention look like? Patent application is required to contain drawings, if drawings are necessary to describe the invention especially product inventions other than chemicals. Drawing(s) should commence on separate sheet(s) and the minimum margins shall be as follows,- Top 2.5 cm Left side 2.5 cm Right side 1.5 cm Bottom 1.0 cm Execute the drawings without coloring in durable, black, sufficiently dense and dark, uniformly thick and well-defined lines and strokes to permit satisfactory reproduction. Flow sheets and diagrams are also considered as drawings for this purpose. Please write in the left-hand top corner of the drawing the name of the applicant and in the right-hand top corner the number of sheets or drawings and the words ‘original’ or ‘true copy’ as the case may require. Similarly in the right-hand bottom corner the signature of the applicant or his Agent is required. Please do not write the title of the invention or any descriptive matter on the drawings. Only numeral references may indicate different parts of diagram (For further details, please see Rule 11 of the Patent Rules 2003). You have to mention reference to the drawing(s) in specification under the heading Brief description of drawings and further elaborate your invention with the help of drawings.

Preparation of Provisional Patent Specification: Option for filing provisional specification is a quick and inexpensive way for inventors to establish a filing date for their in-process invention, which can be claimed later, by filing a complete specification within 12 months. You can file a provisional specification without many of the 9 formalities required for a complete specification. Provisional specification must include contents of complete specification but you may file claims and drawings later on, because provisional specifications are not examined in the Patent Office. An applicant who decides to initially file a provisional specification must file a corresponding complete specification during the 12-month from the filing date, failure to which the provisional specification will automatically abandoned after 12 months of its filing date. A complete specification is examined by a patent examiner. If your invention does not meet the prescribed requirements of patentability or if your application has other limitation, the patent examiner will send you an official communication which is generally referred as Examination Report informing you of any deficiencies. You then have the opportunity to respond and to remedy deficiencies. When all the requirements are met, the patent application proceeds for acceptance
