Patent Application Drafting
What the application must contain
An Israeli application needs a request, a specification, claims, an abstract, drawings where necessary, and any sequence listing or deposit information. The specification must describe the invention and enable a skilled person to carry it out; the claims must define the matter for which protection is sought. A priority claim should be made in time and the priority document supplied as required. The drafting goal is a claim set with a broad independent claim, supported fallbacks, and a description that gives examples and definitions.
Claim architecture
Draft independent claims by technical features, not by desired result. Add dependent claims for preferred ranges, embodiments and alternative features. Check support in the description for every claim. Avoid unnecessary limitations in the independent claim, but do not rely on vague functional language to cover unknown embodiments.
Worked example
The disclosure describes a filter with pores of 1-5 microns and a binder. An independent claim to 'a filter comprising pores of 1-5 microns and a binder' is supported. A broader claim to 'a filter with small pores' is unclear and unsupported. A dependent claim to 'pores of 2-3 microns' provides a fallback if the broad range is attacked.
Traps
Adding matter after filing is fatal; amend only within the original disclosure. Do not confuse the abstract with the claims. Do not copy a foreign claim set without checking Israeli practice, unity and claim fees. Ensure the description explains how to make and use each claimed alternative.
