  • Identify small inventors
  • Are they patenting more or less
  • Has AIA helped them

  • count of patents by type by year
  • count of citations of type by year
  • mean term of patents granted by year

Want to create a new table with all small and micro patents and if they are small or micro

Then find all patents citing a small or micro patent

basically a left join of the table and the citations table (so including small micro or large designation is shown)

Look to see how many patents cite knowledge used by small or micro firms

break down by category small medium large

Patent Database

created citation_cleaned table which removed all rows with NULL value in either column

Created citations_made table which counts the number of patents cited by a patent

Created times_cited which counts the number of times a patent is cited

DROP TABLE citation_cleaned
CREATE TABLE citation_cleaned AS
  SELECT patent, cited
  FROM citation
  citation is NOT NULL);
#SELECT 74164171

ALTER TABLE citation_cleaned RENAME patent to citing;

DROP TABLE citations_made
CREATE TABLE citations_made AS
  SELECT citing, count(*) as numcitations FROM citation_cleaned GROUP BY citing;
#SELECT 5214098

DROP TABLE times_cited
CREATE TABLE times_cited AS
  SELECT cited, count(*) as citednum FROM citation_cleaned GROUP BY cited;
#SELECT 6977741

ALTER TABLE citations_made RENAME citing to patent;
ALTER TABLE times_cited RENAME cited to patent;

originality vs generality and whole, jaffey, tratjenberg. 4 standard measures : citations made, received, originality, generality.

citations across classes.

Whole (2005) paper that corrects the bias inherent in those measure,

Built initialsize1 table which had each patent and it's size at first fee event and it's grant date.

Also have an excel sheet with the number of patents granted of each size by year

Joined initialsize1 and citation_count to get the number of citations on and by each patent with the size and grant date.
