MPEP 2100 – Patentability (4)

For inventions with no known utility, certain types of testing are allowed as experimental use. The MPEP 2133.03(e)(6) provides guidance on this:

“[W]here an invention relates to a chemical composition with no known utility, i.e., a patent application for the composition could not be filed (35 U.S.C. 101; 35 U.S.C. 112(a) or pre-AIA 35 U.S.C. 112, first paragraph), continued testing to find utility would likely be permissible, absent a sale of the composition or other evidence of commercial exploitation.”

This means that for inventions lacking a known utility, ongoing experimentation to discover a utility is generally allowed and won’t be considered public use or sale. However, any commercial exploitation during this period could jeopardize the experimental nature of the activity.

What are the key factors in determining if an activity qualifies as experimental use?

Determining whether an activity qualifies as experimental use involves considering several factors. According to MPEP 2133.03(e), key factors include:

  • The nature of the activity
  • The length of the test period
  • Whether payment was made for the device
  • Whether there was a secrecy agreement
  • Whether records were kept
  • Who conducted the experiments
  • The degree of commercial exploitation during testing

The MPEP states, “Once alleged experimental activity is advanced by an applicant to negate a pre-AIA 35 U.S.C. 102(b) rejection, the examiner must determine whether the scope and length of the activity were reasonable in terms of the experimental purpose intended by the applicant and the nature of the subject matter involved.” This assessment helps distinguish genuine experimentation from activities that might trigger the public use or on-sale bar.

The intent of the inventor is not sufficient alone to determine whether a public use or on-sale bar applies. As stated in MPEP 2133.03(e)(2):

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention.”

This means that objective evidence is crucial in determining whether a use or sale was experimental, rather than commercial. The inventor’s secret intent is not enough to overcome a statutory bar.

The level of supervision during experimental use can significantly impact whether an activity is considered public use under patent law. According to MPEP 2133.03(e)(5):

“The degree of supervision and control over the invention required of the inventor to establish experimental use is generally high.”

This means that inventors must maintain substantial control over their invention during testing to ensure it qualifies as experimental use rather than public use. Lack of proper supervision may lead to the activity being classified as public use, potentially affecting patent rights.

MPEP 2133.03(E) – Permitted Activity; Experimental Use (1)

What are the key factors in determining if an activity qualifies as experimental use?

Determining whether an activity qualifies as experimental use involves considering several factors. According to MPEP 2133.03(e), key factors include:

  • The nature of the activity

  • Whether payment was made for the device
  • Whether there was a secrecy agreement
  • Whether records were kept

MPEP 2133.03(E)(2) – Intent (1)

The intent of the inventor is not sufficient alone to determine whether a public use or on-sale bar applies. As stated in MPEP 2133.03(e)(2):

“When sales are made in an ordinary commercial environment and the goods are placed outside the inventor’s control, an inventor’s secretly held subjective intent to ‘experiment,’ even if true, is unavailing without objective evidence to support the contention.”

MPEP 2133.03(E)(5) – Experimentation And Degree Of Supervision And Control (1)

The level of supervision during experimental use can significantly impact whether an activity is considered public use under patent law. According to MPEP 2133.03(e)(5):

“The degree of supervision and control over the invention required of the inventor to establish experimental use is generally high.”

This means that inventors must maintain substantial control over their invention during testing to ensure it qualifies as experimental use rather than public use. Lack of proper supervision may lead to the activity being classified as public use, potentially affecting patent rights.
