Patents At Mach(Final)

  1. 1. Patents at Mach 2: Technology on the Cutting Edge Drexel Experience in a Biomedical Engineering class Jay Bhatt, Drexel University June 22, 2008 American Society for Engineering Education
  2. 2. Drexel’s Engineering Programs <ul><li>All major engineering disciplines </li></ul><ul><li>Biomedical engineering, Science, and Health systems </li></ul><ul><li>Interdisciplinary focus is increasing (Nanotechnology, Biomaterials, Bionanotechnology, Biomechanics, etc.) </li></ul><ul><li>Undergraduate Research </li></ul><ul><li>Graduate Research </li></ul>
  3. 3. Case Study - Biomaterials <ul><li>Course Sequence </li></ul><ul><ul><li>3 Quarters = 2 Semesters </li></ul></ul><ul><li>Challenges </li></ul><ul><ul><li>Interdisciplinary Field </li></ul></ul><ul><ul><li>Diverse Student Background </li></ul></ul><ul><ul><li>Lack of appropriate textbooks </li></ul></ul>
  4. 4. Biomaterials courses – Biomaterials I – Fall Term <ul><li>Prof. Papazoglou teaches the three course sequence </li></ul><ul><li>60-70 students </li></ul><ul><li>Biomaterials properties </li></ul><ul><li>Various types of materials such as polymers, hydrogels, ceramics, and glasses </li></ul><ul><li>Controlled Drug Release systems </li></ul>
  5. 5. Biomaterials courses – Biomaterials II – Winter Term <ul><li>Patents and Intellectual property </li></ul><ul><li>Students needed to use what they learned in the Fall term as well as search for patents </li></ul><ul><li>Cancer nanotechnology as an example </li></ul><ul><li>Group Projects </li></ul><ul><li>Blog site for patents </li></ul>
  6. 6. Biomaterials courses – Biomaterials II – Winter Term <ul><li>Student Assignment List and briefly describe 5 patented technologies for controlled drug delivery in cancer chemotherapy (last 7 years) </li></ul><ul><li>List and briefly describe any patent on drug delivery based on nanotechnology for drug delivery of cancer chemotherapy (last 5). </li></ul><ul><li>Determine uniqueness of each patent </li></ul><ul><li>Find research literature using sources learned during the Fall term </li></ul>
  7. 7. Patent searching <ul><li>Using US Patents-Advanced Feature </li></ul><ul><ul><li>ABST/(Cancer and Drug and Delivery) </li></ul></ul><ul><ul><li>ABST/(controlled and drug and delivery) and (cancer and chemotherapy) </li></ul></ul><ul><ul><ul><li>ABST-Abstract field that contains brief summary of patent invention </li></ul></ul></ul><ul><ul><ul><li>The abstract contains many of the relevant words of a patent </li></ul></ul></ul><ul><li>United States Patent 7,303,739 Erion,   et al. December 4, 2007 Prodrugs for liver specific drug delivery. See handout. </li></ul>
  8. 8. Patent Searching <ul><li>Patent Classification </li></ul><ul><li>Current U.S. Class:424/9.1 ; 424/1.11; 424/1.65; 424/600; 424/601; 424/9.2; 514/7 </li></ul><ul><li>Observe U.S. Classes. </li></ul><ul><ul><li>What is a classification schedule? </li></ul></ul><ul><ul><ul><li>Patents are classified ( organized ) in the U.S. by a system using a 3 digit class and a 3 digit subclass </li></ul></ul></ul><ul><ul><ul><li>They describe every similar grouping of patent art. </li></ul></ul></ul><ul><ul><ul><li>A single invention may be described by multiple classification codes </li></ul></ul></ul><ul><ul><ul><li>For example, Class:424/9.1 ; 424/1.11; 424/1.65; 424/600; 424/601; 424/9.2; 514/7 </li></ul></ul></ul><ul><ul><li>See Classification Help and Glossary </li></ul></ul><ul><ul><li>How does classification help in searching for patents? </li></ul></ul>
  9. 9. Patent Searching using classes and subclasses <ul><li>United States Patent 7,303,739 Prodrugs for liver specific drug delivery. See handout </li></ul><ul><li>Current U.S. Class:424/9.1 ; 424/1.11; 424/1.65; 424/600; 424/601; 424/9.2; 514/7 </li></ul><ul><li>From USPTO site, go to Class Numbers Only Page </li></ul><ul><li>(Path: Patents > Guidance, Tools, and Manuals > Classification US Classes by Number Menu) </li></ul><ul><li>Class   424 : DRUG, BIO-AFFECTING AND BODY TREATING COMPOSITIONS Subclass   9.1           IN VIVO DIAGNOSIS OR IN VIVO TESTING </li></ul><ul><li>Clicking on ‘P’ retrieves all patents for class 424 subclass 9.1. </li></ul><ul><li>Similarly other patents in different classes can be found </li></ul>     
  10. 10. Patent Searching <ul><li>European Patent Office – World Patents </li></ul><ul><li>European Patent Office - Advanced Search </li></ul><ul><ul><li>‘ Cancer Drug Delivery’ as a keyword </li></ul></ul><ul><ul><li>NANOPARTICLES FOR CYTOPLASMIC DRUG DELIVERY TO CANCER CELLS </li></ul></ul><ul><ul><li>  Inventor:  RADOSZ MARCIEJ (US); SHEN YOUQING (US); (+1)  Applicant:  UNIV WYOMING (US); RADOSZ MARCIEJ (US); (+2)   EC:   A61K9/51 IPC:   A61K9/14 ; A61K9/14   Publication info:   WO2007001356  - 2007-01-04 </li></ul></ul><ul><ul><li>Complex drug delivery composition and method for treating cancer </li></ul></ul><ul><ul><li>  Inventor:  MINKO TAMARA (US); SINKO PATRICK J (US); (+1)  Applicant:     EC:   A61K47/48H4P ; A61K47/48R IPC:   A61K47/48 ; A61K47/48 ; (IPC1-7): A61K38/17   Publication info:   US2005043215  - 2005-02-24 </li></ul></ul>
