Q: What are the two main aspects of a requirement to restrict in patent applications?

According to MPEP 808 , every requirement to restrict has two main aspects: (A) The reasons why each invention as claimed is either independent or distinct from the other(s) (B) The reasons why there would be a serious search and/or examination burden on the examiner if restriction is not required The MPEP states: " Every requirement to restrict has two aspects: (A) the reasons (as distinguished from the mere statement of conclusion) why each invention as claimed is either independent or distinct from the other(s); and (B) the reasons why there would be a serious search and/or examination burden on the examiner if restriction is not required ." This emphasizes that examiners must provide specific reasons for both the independence/distinctness of inventions and the potential burden, rather than just stating conclusions.

Q: What are defensive publications in patent examination?

Defensive publications, as mentioned in MPEP 901.06(d) , are documents published to establish prior art without pursuing patent protection. The MPEP states: "Defensive Publications, which are patent applications voluntarily published without examination, are included in the search files." These publications serve as a defensive strategy to prevent others from patenting similar inventions. They are considered prior art and are included in patent examiners' search files for reference during the examination process.

Question 1

What type of paper should be used for plant patent drawings?

Accepted Answer

The type of paper used for plant patent drawings is specified in 37 CFR 1.84(e), as referenced in MPEP 1606. The requirements are:

"Drawings submitted to the Office must be made on paper which is flexible, strong, white, smooth, non-shiny, and durable. All sheets must be reasonably free from cracks, creases, and folds. Only one side of the sheet may be used for the drawing. Each sheet must be reasonably free from erasures and must be free from alterations, overwritings, and interlineations."

Additionally, for photographs:

Photographs must be developed on paper meeting the sheet-size requirements
They must also meet the margin requirements

These requirements ensure that the drawings are of high quality and can be properly scanned, reproduced, and preserved by the USPTO. Using the correct type of paper helps maintain the integrity of your plant patent application throughout the examination process and beyond.

Question 2

Is there a fee for rectifying obvious mistakes in a PCT application?

Accepted Answer

Generally, there is no fee for rectifying obvious mistakes in a PCT application. According to MPEP 1836:

"Any such rectification is free of charge."

However, it's important to note that while the rectification itself is free, there may be a fee associated with publishing a refused request for rectification. The MPEP states:

"Where the competent authority refuses to authorize a rectification under Rule 91.1, the International Bureau shall, upon request submitted to it by the applicant within two months from the date of the refusal, and subject to the payment of a special fee whose amount shall be fixed in the Administrative Instructions, publish the request for rectification, the reasons for refusal by the authority and any further brief comments that may be submitted by the applicant, if possible together with the international application."

Therefore, while rectification itself is free, applicants should be aware that there may be costs associated with challenging a refusal to authorize a rectification.

Accepted Answer

According to MPEP 808, every requirement to restrict has two main aspects:

(A) The reasons why each invention as claimed is either independent or distinct from the other(s)
(B) The reasons why there would be a serious search and/or examination burden on the examiner if restriction is not required

The MPEP states: "Every requirement to restrict has two aspects: (A) the reasons (as distinguished from the mere statement of conclusion) why each invention as claimed is either independent or distinct from the other(s); and (B) the reasons why there would be a serious search and/or examination burden on the examiner if restriction is not required." This emphasizes that examiners must provide specific reasons for both the independence/distinctness of inventions and the potential burden, rather than just stating conclusions.

Question 4

What is the "broadest reasonable interpretation" approach in patent searching?

Accepted Answer

The "broadest reasonable interpretation" approach in patent searching refers to the strategy of interpreting claim language broadly when conducting a prior art search. According to MPEP 904.03:

"The search should cover the claimed subject matter and should also cover the disclosed features which might reasonably be expected to be claimed."

This approach ensures that examiners consider a wide range of potentially relevant prior art, not just documents that match the exact claim language. It helps to identify art that might be applicable under various claim interpretations and potential amendments.

Question 5

What classification systems are used in patent searches?

Accepted Answer

Patent searches utilize multiple classification systems to organize and search for prior art. According to MPEP 904.02(a), the main classification systems used are:

Cooperative Patent Classification (CPC)
U.S. Patent Classification (USPC)
Other organized systems of literature

The MPEP states:

"Every group/subgroup and secondary classification area of the Cooperative Patent Classification, class/subclass of the U.S. Patent Classification, digest, and cross-reference art collection pertinent to each type of invention claimed should be included, from the largest combination through the various subcombinations to the most elementary part."

Examiners should consider all relevant classification areas across these systems to ensure a comprehensive search.

Question 6

What are the consequences of a lack of unity of invention in an international application?

Accepted Answer

What are the consequences of a lack of unity of invention in an international application?

When the International Searching Authority (ISA) determines that an international application lacks unity of invention, it can have several consequences. According to MPEP 1850:

"If the International Searching Authority finds that the international application does not comply with the requirement of unity of invention, it shall inform the applicant accordingly and invite the applicant to pay additional fees."

The main consequences include:

The applicant may be required to pay additional search fees for each additional invention
If additional fees are not paid, the ISA will only search the first claimed invention
The applicant can pay fees under protest and request a review of the unity of invention determination
Lack of unity may affect the international preliminary examination and national/regional phase processing

It's important to note that the lack of unity does not necessarily mean the application is invalid, but it may require the applicant to divide the application or limit the claims to maintain unity of invention.

Question 7

How does the CPC system benefit patent examiners and applicants?

Accepted Answer

The Cooperative Patent Classification (CPC) system offers several benefits to both patent examiners and applicants:

Standardized Classification: It provides a unified system for categorizing patent documents across the USPTO and EPO.
Improved Search Efficiency: Examiners can conduct more comprehensive prior art searches using a harmonized classification system.
International Consistency: Applicants benefit from consistent classification across multiple patent offices, potentially streamlining international patent applications.
Enhanced Accessibility: As mentioned in MPEP 905, the CPC is "available for public search for classification," allowing applicants to better understand and navigate the patent landscape.

These benefits contribute to a more efficient and transparent patent examination process, potentially leading to higher-quality patents and reduced examination times.

Question 9

How does the examiner determine if a Markush claim is too broad?

Accepted Answer

How does the examiner determine if a Markush claim is too broad?

An examiner determines if a Markush claim is too broad by assessing whether the claim encompasses a large number of independent and distinct inventions. According to MPEP 803.02:

"If the members of the Markush group are sufficiently few in number or so closely related that a search and examination of the entire claim can be made without serious burden, the examiner must examine all the members of the Markush group in the claim on the merits, even though they may be directed to independent and distinct inventions."

However, if the Markush group contains a large number of alternatives or widely diverse elements, the examiner may determine that a serious search burden exists and require an election of species.
