1.2 Identifying Patentable Inventions
When reviewing an invention disclosure or conversing with an inventor, the patent drafter's primary focus must be on identifying and articulating the patentable inventions described. It is common for invention disclosures and discussions to encompass not only details of potentially patentable subject matter but also non-patentable technical information. Inventors frequently perceive their creations as mere "discoveries" rather than inventions in the statutory sense. They might mistakenly believe that their physical prototype or a specific embodiment of the invention constitutes the invention itself and therefore require guidance to explore the underlying novel and inventive concept. Consequently, it is often the patent drafter's role to conceptualize and articulate what precisely constitutes the patentable invention the core inventive concept.
A fundamental principle is that the patentability of an invention cannot be properly assessed without a thorough understanding of the prior art. Engaging with the inventor to explore the specific problem they believe their invention solves, particularly in light of the existing prior art, is instrumental in helping the drafter to formulate the essential elements of the patent claims.
Example:
An inventor states that they have combined the well-known Widget A with Widget B. Subsequently, they heated the common edge where these two widgets meet for 5-10 minutes, after which they used epoxy to attach Widget C to the treated common edges of Widgets A and B.
Upon investigation, the patent drafter discovers that the combination of Widget A and Widget B attached to Widget C is previously unknown. Suspecting that this specific combination might possess the requisite novelty and inventive step (i.e., be novel and non-obvious), the patent drafter inquires whether the inventor has ever encountered any prior attempts to combine these particular widgets.
The inventor confirms that others have indeed attempted for years to combine these widgets, with some limited success. However, a persistent issue has been that Widget C invariably separated from Widgets A and B after a short period.
The patent drafter then asks whether the solution lies in the step of heating the common edge, to which the inventor affirms its correctness.
Based on this exchange, the patent drafter recognizes that a distinct patentable invention consists of: Widget A coupled to Widget B, subjected to heat treatment along their common edge prior to the application of Widget C.
Professional Tip:
Never assume an inventor possesses a complete understanding of what constitutes their invention in patent law terms. Inventors typically conceptualize in terms of products, discoveries, or research outcomes rather than the legal concept of an invention as defined by patent claims. It is essential to ask probing questions to fully grasp the invention, but do so with a collegial and supportive demeanor. Remember, you are not the inventor; your role is to assist the client by effectively describing their invention and subsequently securing appropriately scoped patent protection for it.
1.3 Understanding the Invention: The Core Inventive Concept
The patent drafter's primary objective is not to assume the role of the inventor but rather to achieve the clearest possible grasp of the invention. This deep understanding enables the drafter to prepare a patent application that supports the broadest claims permissible under the law. This necessitates understanding the invention sufficiently to define it using the minimum number of essential elements, thereby discerning which components are critical and which can be omitted from the claims. Comprehending the invention also empowers the patent drafter to prepare an application that discloses all potentially patentable aspects. Crucially, it ensures sufficient additional information is provided so that a person skilled in the art can both understand and effectively carry out the invention. Furthermore, a thorough understanding allows the patent drafter, upon reviewing a prior art reference, to clearly articulate the distinctions between the invention and that prior art, or between the invention and the pending claims. This capability is vital for minimizing the risk of inadvertently narrowing the claim coverage.
Example:
Consider an invention involving Widgets A, B, and C. The inventor's disclosure indicates that the common edge formed by combining Widgets A and B was subjected to burning prior to attaching Widget C. The patent drafter might then inquire whether the surface preparation could involve methods other than burning. If alternative methods are viable, the invention's scope could be broader than solely burning the surface material. For instance, the drafter might question whether the surfaces could be burned before Widget A is attached to Widget B, or if they must be combined first.
Numerous questions arise that the patent drafter can pose to the inventor. The answers to these questions are invaluable for refining the understanding of the invention and subsequently drafting the most effective claims and supporting description.
Naturally, the patent drafter may encounter situations where the inventor lacks definitive answers to all questions. In such cases, the inventor might be able to speculate on alternatives or, in some instances, may have the opportunity to conduct further research. However, it remains imperative that the patent application discloses a working embodiment of the invention. Therefore, if the inventor expresses uncertainty regarding a specific aspect, the patent drafter must exercise their best professional judgment to resolve the ambiguity. This may involve, for example, advising the inventor to consult with a design engineer. While the patent drafter can bridge gaps in the technical disclosure, they must always confirm with the inventor that any added material is accurate and aligns with the fundamental spirit of the invention.
Occasionally, the patent drafter can even assist the inventor in exploring potential alternative embodiments of the invention. Inventors often focus intently on solving a very specific problem and may not have fully considered the broader applicability or potential uses of their invention in other areas.
1.4 Inventorship
A patent application, upon filing, must include the name(s) of the true inventor(s). Prior to this critical step, the patent drafter has a responsibility to inquire with their client about the identity of the inventor(s) and subsequently verify whether the individuals designated by the client meet the legal criteria for inventorship. It is crucial to recognize that the individuals nominated by the client may not always be the actual inventors.
In certain jurisdictions, for instance, it might be customary practice to list all members of a research team as joint inventors, irrespective of the extent of their individual contribution to the invention. Culturally, it may also be commonplace to include, as a gesture of respect, a research and development manager or a lead professor who has made no substantive contribution to the inventive concept itself. The consequences of incorrectly identifying the inventor(s) can be significant after filing. Such errors may lead to challenges based on fraud or misappropriation, potentially rendering a granted patent invalid or unenforceable. They can also complicate the establishment of a priority claim. Because only some jurisdictions permit amendments to incorrect inventorship indications post-filing, it is essential to conduct a thorough verification at this preliminary stage.
While the precise definition of inventorship varies across jurisdictions, the overarching principle within the patent system is that an individual must have made a creative contribution to the inventive concept of the claimed invention. In essence, that person's ingenuity must have directly led, in some way, to the features of the claimed invention that distinguish it from the prior art. For example, in the United States, a person who contributed to the conception of the invention is entitled to be named as an inventor, whereas an individual who merely acted under the direction of that person is not. Similarly, in Japan, only an individual who has substantially engaged in the creative process leading to the claimed invention is recognized as an inventor. Conversely, a supervisor who merely manages inventors, a person who simply follows instructions to collect data or conduct experiments, or an individual who merely provides funding and facilities to the inventor may not be entitled to inventorship.
2 Typical Parts of the Patent Application
Once the patent drafter possesses a firm understanding of the invention, they can commence the preparation of the patent application. This document typically comprises the following sections:
- A request (or application form)
- A description
- Claims
- Drawings
- An abstract
Where the invention involves nucleotide and/or amino acid sequences, a sequence listing, usually in electronic format, may also be required. Furthermore, national and regional patent laws often require the submission of various additional documents and declarations to the respective patent office. These may include a power of attorney, documentation identifying the inventor(s), proof of the applicant's entitlement to apply for or be granted a patent, and an oath or declaration of inventorship. As these requirements differ significantly from one jurisdiction to another, a patent drafter must carefully check the specific rules of each territory in which patent protection is being sought.
2.1 Request
The request section formally declares the applicant's intention to seek patent protection and must be signed by the applicant or their authorized representative. Typically, each patent office provides a dedicated request form (sometimes referred to as a patent application form) that needs to be completed. While these forms vary to reflect the nuances of national or regional legislation, they generally include the following key information:
- The title of the invention.
- The name and address of the applicant and their representative (e.g., a patent attorney or agent).
- An indication of the inventor(s).
- Information pertaining to any priority claim, such as the application number and filing date of the earlier application upon which the priority is based.
As a general rule, all priority-related information, including details about the earlier application for which priority is claimed or information about a parent application in the case of a divisional application, should be included within the patent application. This information can be provided either on the request form itself or within a separate Application Data Sheet (ADS). In the United States, for example, such indications of related applications are typically provided under the heading “CROSS-REFERENCE TO RELATED APPLICATIONS,” appearing early in the application, immediately following the title of the invention.
2.2 Description
The description serves to disclose the invention in sufficient clarity and completeness to enable a person skilled in the art to carry out the claimed invention. To enhance readability, the description is typically structured into several distinct sections. While the precise format of the description can vary between jurisdictions, the following elements are generally included:
- Title of the Invention: As stated in the request, the title concisely identifies and broadly describes the invention for which patent protection is sought. -Technical Field: The technical field to which the invention relates is then specified.
- Background Art: This section outlines the existing knowledge and technology in the field of the invention, which is often helpful for understanding the context and significance of the invention.
- Summary of the Invention: Following the background art, a summary is provided. This outlines the general scope of the invention and explains how it addresses the problems identified in the background art.
- Brief Explanation of the Drawings: The description then briefly explains the accompanying drawings.
- Detailed Disclosure of Embodiments: Finally, the description provides a more detailed disclosure of the claimed invention through specific examples or embodiments, with direct reference to the drawings. These examples are important for fulfilling the support and enablement requirements of patent law (refer to Module II, Section 2.5 for further details).
2.3 Claims
The claims are the heart of the patent application, legally defining the precise scope of exclusive protection sought in terms of the invention's technical features. They are the legally operative part of the application, and the determination of whether an invention meets the patentability requirements is made primarily based on these claims. Claims must be clear, concise, and fully supported by the description. They are typically written in a specific format, for example:
- An apparatus, comprising:
- a pencil having an elongated structure including two ends and a center between the ends;
- an eraser attached to one end of the pencil; and
- a light attached to the center of the pencil.
2.4 Drawings
The drawings provide essential visual support for describing the invention, often facilitating a better understanding of the claimed invention. They may include figures, tables, flowcharts, and diagrams. A representative drawing is commonly featured on the front page of a published patent document.
2.5 Abstract
The abstract is a concise summary, or digest, of the invention, typically limited to a specified word count. It usually highlights the key technical features recited in the claims and primarily serves as an aid for individuals conducting patent searches and for readers reviewing patent documents, providing a brief overview of the invention.
2.6 Application Format
Although these five core parts (Request, Description, Claims, Drawings, and Abstract) are commonly found in the filing requirements of various countries and in international patent applications under the Patent Cooperation Treaty (PCT), their detailed format rarely remains identical across all jurisdictions. For instance, while the description may be divided into several sections, the specific headings used for these sections can differ from one jurisdiction to another. To ensure compliance, some patent offices provide sample application formats that applicants can use as a guide.
