Why Patent information is gaining momentum at
Drexel?

• Drexel, Penn and Ben Franklin partnersform
  Nanotech. Commercialization Group through the
  Nanotechnology Institute
• Facilitate commercialization of IP discoveries by
  NTI member institutions
• Vision for regions economic growth as new
  technologies emerge in the marketplace
• Implications of research and courses being taught
  at Drexel
• Need to increase awareness of patents and patent
  searching is growing fast

Office of Research and Technology
Commercialization

• Drexels Office of Research and Technology
  Commercialization has a mission to commercialize
  Drexel Intellectual Property
• Technology commercialization, especially with the
  addition of the College of Medicine, represents a
  significant opportunity at Drexel.
• The healthcare area is growing rapidly with
  synergies between College of Engineering and
  College of Medicine.
• Plays an important role in the economic
  development of the Philadelphia region.

Drexels Engineering Programs

• Engineering is vital to IP scene at Drexel
• All major engineering disciplines
• Biomedical engineering, Science, and Health
  systems, collaboration with the College of
  Medicine
• Interdisciplinary focus is increasing(Nanotechnol
  ogy, Biomaterials, Bionanotechnology,
  Biomechanics, etc.)
• Graduate and Undergraduate Research

Case Study Biomaterials Course

• Course Sequence
• 3 Quarters 2 Semesters
• Challenges
• Interdisciplinary Field
• Diverse Student Background
• Lack of appropriate textbooks
• Use of electronic books from databases such as
  ENGnetBASE, Knovel and MATERIALSnetBASE

6
Biomaterials courses Biomaterials I Fall Term

• Prof. Papazoglou teaches the three course
  sequence
• 60-70 students
• Biomaterials properties
• Various types of materials such as polymers,
  hydrogels, ceramics, and glasses
• Controlled Drug Release systems
• Students are required to refer to and use peer
  reviewed literature in their final project

7
Biomaterials courses Biomaterials II Winter
Term

• Patents and Intellectual property
• Students needed to use what they learned in the
  Fall term as well as search for patents
• Cancer nanotechnology as an example
• Group Projects
• Blog site for patents

8
Biomaterials courses Biomaterials II Winter
Term

• Student Assignment List and briefly describe 5
  patented technologies for controlled drug
  delivery in cancer chemotherapy (last 7 years)
• List and briefly describe any patent on drug
  delivery based on nanotechnology for drug
  delivery of cancer chemotherapy (last 5).
• Determine uniqueness of each patent
• Find research literature using sources learned
  during the Fall term

9
Patent searching

• Using US Patents-Advanced Feature
• ABST/(Cancer and Drug and Delivery)
• ABST/(controlled and drug and delivery) and
  (cancer and chemotherapy)
• ABST-Abstract field that contains brief summary
  of patent invention
• The abstract contains many of the relevant words
  of a patent
• United States Patent 7,303,739Erion,   et al.
  December 4, 2007 Prodrugs for liver specific
  drug delivery. See handout.

Patent Searching

• Patent Classification
• Current U.S. Class424/9.1 424/1.11 424/1.65
  424/600 424/601 424/9.2 514/7
• Observe U.S. Classes.
• What is a classification schedule?
• Patents are classified (organized) in the U.S. by
  a system using a 3 digit class and a 3 digit
  subclass
• They describe every similar grouping of patent
  art.
• A single invention may be described by multiple
  classification codes
• For example, Class424/9.1 424/1.11 424/1.65
  424/600 424/601 424/9.2 514/7
• See Classification Help and Glossary
• How does classification help in searching for
  patents?

Patent Searching using classes and subclasses
 
 
 

• United States Patent 7,303,739Prodrugs for liver
  specific drug delivery. See handout
• Current U.S. Class424/9.1 424/1.11 424/1.65
  424/600 424/601 424/9.2 514/7
• From USPTO site, go to Class Numbers Only Page
• (Path Patents gt Guidance, Tools, and Manuals gt
  Classification US Classes by Number Menu)
• Class   424 DRUG, BIO-AFFECTING AND BODY
  TREATING COMPOSITIONS Subclass 9.1
           IN VIVO DIAGNOSIS OR IN VIVO TESTING
• Clicking on P
  retrieves all patents for class 424 subclass 9.1.
• Similarly other patents in different classes
  can be found
