patent classes **bug**

[laironald]

it looks as if there are lots of duplicated values/entries in the class file. for example, look at 07012073 in the class.sqlite3. running the following code shows issues:

select count(*) from (select * from class where prim=1 group by patent having count(*)>1);

• Translates to: how many of the patents have more than 1 primary class listed?
• the answer results to: 139,594 which seems a bit weird!

I ran a query on 07012073 in class.sqlite3:

sqlite> select * from class where patent = "07012073";
Patent|Prim|Class|SubClass
07012073|1|514|217.07
07012073|1|514|21707
07012073|0|540|597
sqlite>

Interesting.

This is a good statistic to track in any case.

there are many more examples. i believe this is some duplication error. 21707 looks suspiciously like 217.07...

I'm real curious where that is in the parser...
