Claims format: In 2016 we fixed some content-format issues in the claims section, which were wrong in the original data sources. For example, JP national data is delivered with all claims squashed into claim 1. Also we get some records without claim numbers. The two big claims reloads that we completed are: 5,763,744 JP original language claims and and 1,773,963 WO claims. Total - more than 7.5 million claims fixed.
Euro-PCT records, which have he the same issues than the "parent" PCT records, are going to be reloaded to fix the claims issue.
We plan to complete this reload between Feb 10-20, before the end of February 2017.
Citations: DOCDB used to consolidate all citations at the earliest publication, A1 or A2 kind codes. This changed at some point last year and now citations are no longer consolidated. As a result of this change we are going to reload citations for about 14,5 million records in the upcoming weeks.This reload will fix a related issue, a former limit of 99 in the number of citations. This limit doesn't exist any more and after the reload approximately 173,000 records will have more than 99 patent or non-patent citations.
We plan to complete this reload before the end of March 2017.

We have identified about 2.5 million JP records that were "re-keyed" to fix their publication numbers. The new records were loaded, however the old records were never marked deleted. These effectively duplicate records will be reloaded and marked deleted between Feb 13-17, 2016.

Main Differences Between CD1.5 and CD2.0
- The web service authentication method has changed from httpauth to using the http headers to pass x-user and x-password to the service
- With 2.0, JSON response are now wrapped in a response container so in CD1.5 {responseHeader:...} in CD2.0 is {status: success, time:1 ...content:{responseHeader:....}}
- New reporting service allows authorized users to produce CSV formatted data sets from lists of patent numbers or search results
