Description Requirement

There may be various ways of explaining the description/requirements, but the
   fundamental idea of this principle can be said as follows:

1. You must disclose your invention in an understandable way:
    • A patent is given to an inventor (applicant) in return for disclosure of his
    • If you do not disclose the invention, you cannot have a patent.
    • How should you disclose your invention? By writing.
    • Thus, you need to prepare some documents.

Necessary documents for patent application are:
    • Application form;
    • Claims;
    • Specification;
    • Drawings;
    • Abstract.
2. Application form

Several types of application forms are used in the circumstances, under which the
application is filed, but the most common forms are:

Form P-1            when the inventor is sole or joint applicant.

Form P-1A           when the inventor is not a party to the application

Form P-2            when priority is claimed.

The application form must indicate:

     •   Applicant’s name, address and nationality
     •   Title of the invention
     •   Name, address and nationality of the inventor(s)
     •   Summary of pages of description, claims, abstract, drawings etc.
     •   Address for service in Pakistan
2. Application form

     •   The application form must be complete in all respect. If priority is claimed a
         certified copy of priority document must be filed in the Patent Office alongwith
         the Application. However if it could not be filed alongwith the Application at
         the time of filing the Application for the grant of Patent, it can be filed later on
         but within 9 month from the date of filing of such priority application upon
         filing requests for extension of time and paying the prescribed fee.

The specification, claims, abstract and drawings, must be written in English language.
Pakistani Patent Office accepts the documents particularly the priority documents in
any language but it must accompany its verified English translation. If the English
translation is not filed with the original priority document, it must be filed before the
examination of the patent application.

The specification is the description of the invention. It is drawn up like a story, the plot of
   which should be very simple and must contain:
     • Prior art and its problems;
     • Minimum requirements to solve the problems;
     • Detailed story of the invention;

Since the reader of the specification may be
     • Other inventors
     • Examiners
     • Judges
     • Competitors
     • Ordinary people

Therefore, the specification must be clear and should provide full and correct
   understanding of the invention, where the prior art should also be described in full
   and correct understanding.

Always use scientific and standardized terms so that every one should understand the
   invention in the same way.

The specification must support the claims.
The specification must be arranged in the following manner:
     • The Abstract of the invention.
     • Title of the invention
     • Technical field
     • Background art (prior Act)
     • Summary of the invention
     • Embodiments
     • Brief description of the drawings

The specification can also be prepared in the following manner:
     • The Abstract of the invention.
     • Title of the invention
     • Technical field
     • Background Act
       * Description of the prior art
       * Problems of the prior art
     • Summary of the invention
       * Objects of the invention
       * Means to solve the problem
       * Advantages of the invention
     • Embodiments
     • Brief description of the drawings
The abstract of the invention should be given firstly so that the reader must have
   the idea of the invention before going into its description. It is normally the
   first claim of the invention.

    •   The purpose of the invention is to solve problems of the prior art.

    •   The problems of the prior act should be recognized by the reader of the

    •   The prior art should be described in a manner to enable the reader to
        understand            the problems of the prior art.

    •   Can use drawings to describe the prior art.
When you prepare the “Background Art” section, you should first pick up one (or two)
  prior art, and explain how the prior art apparatus works.

     •   Then point out the problems of the prior art.

     •   Point out only those problems which will be solved by the invention.

     •   Do not write any problems which the invention does not solve.

     •   Always choose well described/good prior art.

     •   The “good prior art” is prior art which fits in the story of the invention.

     •   The story of the invention is a happy-end story; you make the reader
         understand values of the invention. The prior art should be selected for this

     •   Chose a single prior art. The story of the invention starts here. Think yourself

          provides great improvements. The description of the prior art is the starting
What is summary of the invention?

  The summary of the invention is normally the technical measures to solve the
   problems of the prior art. This section is consistent to the claims – usually the
   independent claims are copied here alongwith some of the dependent claims so as
   to make them understandable as the language of the independent claim is often
   very complicated and not easy to understand. The reader may not understand how
   the claim apparatus works if you only describe the structure of the apparatus. Then
   you can add some sentences to explain how the claimed apparatus works.
   Therefore, the summary of the invention may consist of:

    1. Structure of the apparatus

    2. Function of the apparatus

    3. Advantages of the apparatus

   •   An Embodiment is an example of an apparatus which works under a principle
       of the invention.

   •   The Embodiment section is a detailed description of the invention with the help
       of the drawings if any.

   •   In this section every element of the apparatus should be described in such a
       way that firstly the structure of the apparatus be described and then describe

Various ways to protection:

How many independent claims can you make for a product?

    •   Final product;
    •   Intermediate product;
    •   Sub-combination;
    •   Parts of the product;
    •   Method of making the product;
    •   Method of using the product;
    •   Machine for making the product; and
    •   Parts of the machine.
Various ways to protection:

How many independent claims can you make for a product?

    •    Unity of the invention should be maintained.
    •    The unity of invention means how many inventions can be included in a single
    •    According to new Patent Ordinance, 2000 each application shall rotate to one
        invention only.
    •    Claim is definition of the invention (you have to define the invention by words).
    •    Everything written in the claim is the required element of the invention.
    •    Claims should be drafted as broad as possible.
    •    Claims should be supported by the specification as a claim is an abstract idea
        derived from the detailed description.
    •    Since the patent is given to the inventor in return for disclosure of this
        invention, therefore, it is necessary to review the specification and confirm that
        there is sufficient support for the claims.
    •    The claim should cover all embodiments, as the claims determines the scope
        of protection e.g. if two or more embodiments are disclosed in the
        specification, the claim must cover all these embodiments. If the second
        embodiment is not covered by the claims the second embodiments is
        dedicated to the public.
Various ways to protection:

A claim has three parts in its structure, namely
        * Preamble
        * Transition
        * Body

              i.     Preamble is an introductory statement that indicates a subject of
                     the invention and its category. e.g.
                     An apparatus for controlling fuel injection.
              ii.    Transition is a bridging words placed between “preamble” and
                     “body”. E.g. “Comprising”;
              iii.   Body is a part that describes all necessary elements of the
                     invention i.e. a sensor for detecting a flow rate of a fuel supplied to
                     a fuel injector; and a controller for adjusting an opening degree of a
                     value located on a fuel delivery line when the flow rate of the fuel
                     detected by the sensor exceeds a predetermined value.
Various ways to protection:

There are three types of claims:

       * Independent claims
       * Dependent claims
       * Multiple dependent claims

The claims should always be arranged in the manner that the independent claim should
   lead the dependent claims and the multiple dependent claims should follow the
   dependent claims.
