In the early days of Derwent, the users discovered that there was a
limit to the number of IPCs that were added to the file from
subsequently appearing family members. I don't recall what the limit
was (up to 6?), but we eventually got them to change there policy.
In addition, Derwent was aware of the "scattershot" approach to
assignment of IPCs and their long-standing remedy was to create Manual
Codes -- MCs.
Caveat emptor: use any method you can to get retrieval; truncated IPCs,
MCs, text, whatever.

PS: I also agree with the validity of the comment in another response,
"Why should the inventors be concerned with correct IPC coding?"
