Agenda • Lab’s technology and research trajectories • Semantic distance and application to noncompete knowledge flow citation model
• Interface demonstration of (soon to be) weekly updates • Last minute recap for everyone who walked in late
– We’ll be here through and after Heidi’s presentation

Graph of blocking actions in patent applications, from uniform random sampling (~1/50) of PAIR applications. Geron Corporation’s patent number 6,093,809, Telomerase, appears to have blocked three other patent applications. The patent is co-owned by CU Boulder and was invented by Thomas R. Cech, of Boulder CO, and Joachim Lingner, of Epalinges, Switzerland.
Research: blocking networks
Tagging
• Develop list of words that differentiates each patent from claims, abstract, and description
• Application in finding “control” patents • Will demonstrate with Furman-Stern knowledge diffusion model
Tagging - High-Dimensional Feature Selection
• X: of dimension 5 million by 2 million • β: feature vector • y: response vector • Find the very few features that best predict y
Advantage: sparse regression, automatic stop-word removal, computation efficiency
Research: cluster visualizations • Using patent tags, we can “plot” patents in N-dimensions • DBSCAN algorithm
– find clusters of patents with similar tags
• Plot in 2D/3D by projecting patents onto vectors of most differentiating tags (PCA dimensionality reduction)
Demonstration of semantic distance • Many measures of “distance” • Treatment patents = all MI 1975-1984 • Control patents:
– non-enforcing state – within 6 months of treatment – closest technological “distance”
• Expect increase in citations after 1985 – expect mediation by mobile inventors – Mean trmt/cntl cites 2.73 and 3.045 before; 7.86 and 7.67 after.

Technology (Feb. 2014) • ~ Monthly download of grant + application data
– parse, clean, build database1975- (thanks Gabe!) – disambiguation of:
• inventors (whole new algorithm by GC) • geography • Jaro-Winkler assignee and lawyer
– public access via API or .csv query – consistent inventor identifiers
