What is the role of the examiner in assessing the written description requirement?

The examiner plays a crucial role in assessing whether a patent application meets the written description requirement. According to MPEP 2163.02:

“The examiner has the initial burden of presenting evidence or reasoning to explain why persons skilled in the art would not recognize in the original disclosure a description of the invention defined by the claims.”

The examiner’s responsibilities include:

  • Thoroughly reviewing the entire application
  • Analyzing whether the specification provides sufficient support for the claimed invention
  • Providing clear explanations and evidence if a written description rejection is made
  • Considering the applicant’s arguments and evidence in response to rejections

The examiner must make a decision based on the preponderance of evidence, taking into account the nature of the invention and the level of skill in the art.
