1. Patent Drafting
Vinita Radhakrishnan

2. Patent System: Rationale
 Public Good
inventor must provide a complete and
accurate public description of the invention
in order to enable others to use that
information to invent further, thus pushing
technology forward for the benefit of society
 Quid pro quo

3. Patent Drafting
 Skill based
Techno-legal Expertise
 One time chance
Not allowed to add forgotten or missed out
details later
cannot get protection for what is not described
properly

4. The Drafting Dilemma
 Implications of
 Claiming too broadly
 Claiming too narrow
 Claiming just right:
 This is an art and requires lots of imagination
 Claim must be adequately supported by the
description
 Must avoid
 Not claiming what the client wants
 Claiming what the client does not use or need

5. One way road
 Cannot broaden the claims of a granted patent
 Cannot broaden the disclosure and the claims
beyond what has been included when drafting
the application that was filed
 You are responsible for getting the scope of
protection the inventor deserves
You do not get a second chance

6. Patent drafting for India
 Specification Drafting
 Claim Drafting

7. Specification Drafting
 A specification is a techno-legal document
containing scientific information
constituting patent rights.
 Purpose of Specification
Disclose details of the invention for which
protection is sought
Define legal boundaries of the invention for
which protection is sought

8. Sufficiency of Disclosure
Disclosure of an invention in the specification is
intended for a person skilled in the art to
understand and work the invention
 Disclosure
 Support Claims
 Enablement
 Must enable a person skilled in the art to carry out
the invention described in it
 Best Mode
 On the date of invention

9. Clarity of Disclosure

35. Claim Drafting

36. Describe

37. The Cat Sat on the Mat

38. In other words….
“The feline mammal was occupying, in a
sense, a wholly if not entirely
sedentary position within the general
context of what was, as could
clearly be seen in this situation, a
horizontally-spread woven textile
floor-covering, as is sometimes -- but not
always -- the case".

39. Claims
 Claims define the metes and bounds of an
invention
 Claim Limits the extent of protection
 What is not claimed is disclaimed!

40. Parts of claim
 Single sentence ending with a period.
 Three parts
 Introductory Phrase
 Introduces the subject matter of the invention
 Body
 defines a particular embodiment of the invention
 Transition Phrase
 joins the introductory phrase and the body of claim
 Open ended v. close ended claims

41. Example
“I claim a pencil having an eraser fastened
to one end.”
 Introductory phrase - “a pencil”
 Transition phrase – “having”
 Body – “an eraser fastened to one end”
 GENERALIZATION IS THE KEY

42. CLAIM CLASSIFICATION
 Independent Claims

Generally defines the essential novel features
of the most preferred embodiments of a
product or a process.

55. Tips
Pre drafting
 Understand the invention
 Identify the crux of the invention
 Consider all possible embodiments

56. Tips
 Keep the inventor informed.
 Draft Claim outline before starting to draft
the description. Finalize the claim after
specification is drafted
 Avoid Unnecessary information
 Keep in mind the level of PHOSITA while
drafting the claim.

57. Claim Drafting is all about
Precision! Clarity! Imagination! Foresight!

58. Take home for the
day

59. Claim Language

68. Fact Pattern
PANCAKES, is a restaurant chain in Bangalore specializing in
serving breakfast.
In 2004, PANCAKES’ pancake sales dropped. In an effort to
improve pancake sales and increase profits, PANCAKES designed
a new pancake, with a hole in the centre, to hold syrup, butter,
whipped cream, and other toppings, such as fruit. The hole prevents
the toppings from spilling all over the plate. The pancake hole was
the perfect size and shape to hold the ideal amount of toppings and
discourage waste by PANCAKES’ employees and patrons. More
efficient use of toppings, and increased pancake sales, translated
into greater profitability.
PANCAKES marketed the new pancakes under the name
“PuddleCakes™”, and filed patent applications for the concept in
India

69. Prior Art

71. Elements
 Pan cake
 Hole

72. Claims: As filed
 A prepared food item, said food item
having a hole to retain a second food item
when said second food item is placed in
said hole.

73. Amended Claims
 A prepared food item having a top surface, a bottom surface, a
perimeter and a side edge and further provided with a hole
disposed centrally and shaped to retain a second food item
within the hole by forming a substantially circular inner side wall
and a bottom wall from the surrounding first food item, the diameter
of said hole being no more than half of the diameter of the first
food item.
 A pancake prepared on a heated surface and having a top
surface, a bottom surface, a perimeter, and a side edge, said
pancake further including a centrally disposed reservoir adapted to
retain an amorphous topping when said topping is placed in said
reservoir.

74. Kahani mein twist
One day, while eating PuddleCakes at a PANCAKES restaurant, the
CEO of ‘TASTY Foods’, hit upon an idea for increasing his
company’s sales of pre-pressed frozen hamburger patties. His idea
was to place a hole in the centre of the hamburger patties to create
a reservoir for holding condiments, such as mustard, ketchup, and
mayonnaise. The hole prevents the condiments from squeezing out
of the bun. TASTY Foods began selling its pre-pressed, frozen
hamburgers with a hole under the name “PuddleBurgers.”
‘BURGER QUEEN’ a take away joint next to ‘PANCAKES’ in Indira
Nagar started serving puddleburgers as their new arrival into the
take away cuisines.
PANCAKE UNHAPPY. WANTS TO SUE….
