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
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 region’s 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 • Drexel’s 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.
Drexel’s 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(Nanotechnology, 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
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
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
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
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. 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?
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
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
Excercise • Find one patent using class 977/774. • What is the title of the patent you found? • What type of patents are we going to find in this class/subclass combination? • Can we find some information on ‘Nanobot’? “Quantum Dots’? • What other classes/subclasses your patent recommends for additional references? • What is the Current International Class for this patent? • What is the patent application number? When was this patent filed?
