Current Primary Project: Reproducible Patent Data

Day-by-Day (in reverse chronological order)

June 2017

• June 27: write SQL to replicate assignees, extract postcodes for ongoing projects
• June 26: speedup code, abstract in-memory file splitters to avoid repetition and some weird edge cases
• June 25: create mappings for APS, assignment properties, XML 2.5 for data import; run data imports for granted data
• June 23: cleanup hacky models with a better set of abstractions; cleanup IDE warnings; redefine patent-address mapping
• June 22: create postcode<->patent table
• June 21: document granted patent queries and equivalencies
• June 20: sketch out APS driver; discuss patent id problem; further document with evidence the zipcode data validity
• June 19: skim address regular expressions; cursory investigation of patent table
• June 16: create method of getting all data into the database, whether it likes it or not; copy over assignments, granted data using new scheme
• June 15: add more robust error reporting, fix race conditions; build out assignment driver; build out fee event driver; add error logging
• June 14: migrate bulk inserts to copy command; refresh on address data and start in on that; convert processor to multi-threaded application
• June 13: spot check SQL tables; fix broken final case endlessly looping; investigate smarter insert methods
• June 12: add XML printer, use it to inspect applications; extend BaseScraper to fetch patent application data; add applications documentation to my project page; add CREATE of other tables
