Intersection of Biotechnology and Mechanical Arts
An example of a biotechnology class associated with the mechanical arts is Class 435-Chemistry: Molecular Biology and Microbiology
An example of a mechanical class associated with biotechnology arts is Class 623- Prosthesis (i.e., Artificial Body Members), Parts Thereof, or Aids and Accessories Therefor

Class 435Class 435
Over 172,000 patents & published applications
Within these 172,000 references, over 8,000 disclose at least one of the following delivery devices:
Stent, prosthetic or prosthesis.

Class 623Class 623
Nearly 30,000 patents & published applications, including stents, prosthetics and prostheses.

Areas of Overlapping ArtAreas of Overlapping Art
Stents and prosthetics are just some of the possible devices found in the mechanical art that can be used for delivery of body treating compositions.
Other delivery devices, such as syringes, are less often claimed in combination with the treating compositions.

Coatings for eluting therapeutic Coatings for eluting therapeutic compositions on stents. These therapeutic compositions on stents. These therapeutic compositions may act as anti-thrombotics, compositions may act as anti-thrombotics, antibiotics, and anti-inflammatories etc.antibiotics, and anti-inflammatories etc.

Purposes of ClassificationPurposes of Classification
For administrative and examination For administrative and examination purposes (e.g., ensuring the examination of purposes (e.g., ensuring the examination of patent applications by the best qualified patent applications by the best qualified examiner on the subject matter, restricting examiner on the subject matter, restricting patent applications to properly related patent applications to properly related inventions, interference or infringement inventions, interference or infringement searches, etc.), there is a need to designate searches, etc.), there is a need to designate for U.S. patents a primary, or Original, for U.S. patents a primary, or Original, classification. classification.

1. A coating for a vascular graft having a polymeric external surface comprising: a biologically active surface which exhibits cell attachment activity and growth activity, said surface having linked thereto the expressed protein of a vector. 2. The coating of claim 1, wherein said vector contains a DNA sequence of cDNA coding for the A chain of laminin.

Within the overlap of biotechnology and mechanical arts, an issue sometimes occurs wherein a claim recites an apparatus (as opposed to a method) with certain elements “attached to” the human body or specific body parts.
Combinations Including Parts of the Human Body
27
Functional Recitations
Limitations to parts of the human body presents no problem as long as the language is recited in the format “adapted to be attached” or “for attachment to” or in some similar way which does not positively set forth the human body or portions thereof as part of the claimed subject matter.
28
Claimed Combination
But what about those situations where the portion of the human body is actually set forth as part of the claimed combination?
29
MPEP 2105- Patentable Subject Matter
If the broadest reasonable interpretation of the claimed invention as a whole encompasses a human being, then a rejection under 35 USC 101 must be made indicating that the claimed invention is directed to nonstatutory subject matter.
30
On April 7, 1987, then Assistant Secretary and Commissioner of Patents and Trademarks,
Donald J. Quigg, set forth PTO policy on this issue in the form of a notice entitled “Animals – Patentability”.
Animals-Patentability Animals-Patentability
31
Animals-PatentabilityAnimals-Patentability
The notice stated that the “Patent and Trademark Office would now consider nonnaturally occurring non-human multicellular living organisms, including animals, to be patentable subject matter within the scope of 35 U.S.C. 101”
32
Animals-PatentabilityAnimals-Patentability
The Commissioner stated that a “claim directed to or including within its scope a human being will not be considered to be patentable subject matter under 35 U.S.C. 101” since the grant of a limited, but exclusive property right in a human being is prohibited by the Constitution.
33
Claimed Combination
Accordingly, where a claim is directed to apparatus “attached to” the human body or any part thereof an examiner is to reject such claim under 35 U.S.C. 101.
34
112 1st Paragraph
However, claims which contain language “attached to” a part of the human body raise an issue under 35 U.S.C. 101 but do not inherently raise questions of enablement or indefiniteness.

ExampleExample
An intravascular stent which is permanently implanted in the vessel lumen of a patient and which is used for locally delivering genes in a vessel comprising: (a) a substrate, (b) a coating adhering to the substrate, and (c) a genetic material which is adsorbed to the surface of the coating, wherein the coating comprises a matrix of randomly interconnected protein molecules comprising one or more species of protein.
