<\/span><\/h4>\n\n\n\nA dependent claim incorporates everything in the parent claim by reference and adds certain additional statements, limits, or restrictions. The statements added may be one or more additional elements, a further description or limitation of one or more of the elements of the parent claim, or both. As a result, dependent claims limit the scope of the claim and the extent of an invention\u2019s protection.<\/p>\n\n\n\n
The test to determine whether a claim is a dependent one or not should be as follows – it must incorporate all limitations of the claim form on which it is based, or in other words, it cannot be infringed by anything that would also not violate the fundamental claim.<\/p>\n\n\n\n
Thus, if Claim 1 has features A, B, and C, and a subsequent Claim 2 replaces feature C with feature D so that Claim 2 has features A, B, and D, then claim 2 could not be a dependent claim on Claim 1. In this case, Claim 2 may only be written in the form of an independent claim.<\/p>\n\n\n\n
It is preferable to add an independent claim to maximize claim coverage when an invention includes several features whose inclusions are mutually exclusive (you can include one without having to include the other), rather than attempting to provide coverage solely through a dependent claim.<\/p>\n\n\n\n
The main benefit of dependent claims is that they take significantly less time to evaluate, and carry a financial incentive. Furthermore, if any claim is accepted, all dependent claims can be accepted without further scrutiny for novelty or obviousness.<\/p>\n\n\n\n
<\/span>(e) Reference in Multiple Dependent Form<\/span><\/h3>\n\n\n\n\u201cA claim in multiple dependent form shall contain a reference, in the alternative only, to more than one claim previously set forth and then specify a further limitation of the subject matter claimed. A multiple dependent claim shall not serve as a basis for any other multiple dependent claim. A multiple dependent claim shall be construed to incorporate by reference all the limitations of the particular claim in relation to which it is being considered.\u201d<\/p>\n\n\n\n
While writing the multiple dependent claims, the patent drafters must ensure that the claims refer to the other claims on which they are dependent in the alternative way only, such as \u201cor\u201d instead of \u201cand.\u201d<\/p>\n\n\n\n
<\/span>What are multiple dependent claims?<\/span><\/h4>\n\n\n\nGenerally, these are dependent claims that refer back to more than one preceding independent or dependent claim. Multiple dependent claims are equivalent to the number of claims on which they rely, rather than individual claims. For instance, if a claim is dependent on three other claims, then we have a total of three new claims instead of one.<\/p>\n\n\n\n
Example:<\/p>\n\n\n\n
\n- Claim 1: A right-hand door with a handle in the center.<\/li>\n\n\n\n
- Claim 2: The handle on the door of claim 1 is bolted from the inside.<\/li>\n\n\n\n
- Claim 3: The handle on the door in claim 1 or 2 is made of leather.<\/li>\n<\/ul>\n\n\n\n
Here, Claim 1 is an independent claim, Claim 2 is reliant on claim 1, and Claim 3 refers to both claims 1 and 2, resulting in a multiple dependent claim.<\/p>\n\n\n\n
Apart from dependent and multiple dependent, there are independent claims. An independent claim is a claim that stands alone and has all of the specifications that are required to define an invention. The first claim is often a stand-alone claim that establishes the tone for the invention\u2019s protection. Independent claims are typically more extensive than dependent claims.<\/p>\n\n\n\n
<\/span>(f) Element in Claim for a Combination<\/span><\/h3>\n\n\n\n\u201cAn element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.\u201d<\/p>\n\n\n\n
This means that clauses are proper in combination claims. They are a quick and easy approach to describe a wide range of functions. To invoke that statute, we may use \u201cmeans\u201d or \u201cstep\u201d for performing a specified function like \u201cmeans for reciprocating the container.\u201d A \u201cmeans\u201d or \u201cstep\u201d clause may theoretically cover one element, 10,000 elements, half of one element or it may cover whatever is described in the specification, plus equivalents. However, since the scope of \u201cmeans\u201d or \u201cstep\u201d may be restricted, as just indicated, it is recommended that the drafter avoids these claim limitations and instead give the element or step an appropriately descriptive name, not including the words \u201cmeans\u201d or \u201cstep.\u201d<\/p>\n\n\n\n
<\/span>Conclusion<\/span><\/h2>\n\n\n\nThe above-mentioned details about 35 U.S.C. \u00a7 112 explain how an invention must be described in a patent application. A proper execution of these actions and approaches can help garner a desirable outcome for the applicant. Drafting a patent application is a daunting task. Hence, it is advisable to take the help of an IP firm that can assist in getting the grant fairly, quickly, and with less effort.<\/p>\n\n\n\n
