  1. Patents at Mach 2: Technology on the Cutting Edge Drexel Experience in a Biomedical Engineering class Jay Bhatt June 22, 2008 American Society for Engineering Education

  2. Drexel’s Engineering Programs All major engineering disciplines Biomedical engineering, Science, and Health systems Interdisciplinary focus is increasing(Nanotechnology, Biomaterials, Bionanotechnology, Biomechanics, etc.) Undergraduate Research Graduate Research

  3. Case Study - Biomaterials • Course Sequence • 3 Quarters = 2 Semesters • Challenges • Interdisciplinary Field • Diverse Student Background • Lack of appropriate textbooks

  4. 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

  5. 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

  6. Biomaterials courses – Biomaterials II – Winter Term Student Assignment List 5 patented technologies for drug delivery in cancer treatment (last 7 years) List any patent on drug delivery based on nanotechnology for drug delivery of cancer treatment (last 5). Determine uniqueness of each patent Find research literature using sources learned during the Fall term

  7. Patent searching • Using US Patents-Advanced Feature • ABST/(Cancer and Drug and Delivery) • 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.

  8. Patent Searching • Patent Classification Current U.S. Class:424/9.1 ; 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, Class:424/9.1 ; 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?

  9. Patent Searching using classes and subclasses • United States Patent 7,303,739Prodrugs for liver specific drug delivery. See handout Current U.S. Class:424/9.1 ; 424/1.11; 424/1.65; 424/600; 424/601; 424/9.2; 514/7 From USPTO site, go to Class Numbers OnlyPage (Path: Patents > Guidance, Tools, and Manuals > Classification US Classes by Number Menu) Class   424: DRUG, BIO-AFFECTING AND BODY TREATING COMPOSITIONS Subclass9.1 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

  10. Patent Searching • European Patent Office – World Patents European Patent Office - Advanced Search • ‘Cancer Drug Delivery’ as a keyword • NANOPARTICLES FOR CYTOPLASMIC DRUG DELIVERY TO CANCER CELLS Inventor: RADOSZ MARCIEJ (US); SHEN YOUQING (US); (+1) Applicant: UNIV WYOMING (US); RADOSZ MARCIEJ (US); (+2)  EC:A61K9/51IPC:A61K9/14; A61K9/14Publication info:WO2007001356 - 2007-01-04 • Complex drug delivery composition and method for treating cancer Inventor: MINKO TAMARA (US); SINKO PATRICK J (US); (+1) Applicant:EC:A61K47/48H4P; A61K47/48RIPC:A61K47/48; A61K47/48; (IPC1-7): A61K38/17  Publication info:US2005043215 - 2005-02-24
