Re: Count number of patent applications and citations per company

Hello Xiaohan,
that query creates a too heavy load on the server and it is automatic cancelled because it takes too much resources on the server. (There is a build in limitation to avoid the system working on a query for more then one hour.)
I run it on an my local system and it took about 4 hours. The result generates millions of rows, and even more during the execution of the query. As you said yourself, there are not much restrictions in the query to narrow down the generated data set.
As a matter of exception, i have posted the results here (csv file).
The file will stay available for 30 days.

Much appreciated!!

I am planning to purchase PATSTAT online database, will this large load of query code work properly after the purchase?

Best,
Xiaohan

Dear Community,

Query killed has appeared once again, and I'm not sure if this time it's due to a syntax problem or an overload.
The IPC symbol is massive and detailed and I'm sure I put all the slashes "/" in the 9th position.

Here is my query code, could you check it for me please?

Code: Select all

SELECT psn_id, psn_name, ipc_class_symbol,
COUNT(distinct(case when t1.appln_filing_year = 1980 then t1.appln_id end)) as '1980',
