Why would a corporation file a continuation that consists of one large claim?

0

I've found an allowed continuation to a parent patent application, in which the continuation contains a single claim that appears to be one long concatenation of the original 20 claims of the parent application.

Why would a corporation file such a continuation?

Here is a link to the continuation: US Patent Application 20180227119 (continuation)
And here is a link to the patent: US Patent Application 20180227119 (patent)

Could you provide the two patent numbers? – Eric S – 2018-08-17T13:59:47.430

15/851879 which is a continuation of 15/429121 – Keir Finlow-Bates – 2018-08-17T14:41:42.837

Embedding links in your question makes it much more convenient for people to answer your question. – Eric S – 2018-08-17T14:44:51.767

I didn't think the actual two applications were relevant. The later has one claim, which is the 20 claims of the parent combined into a single claim. Presumably there was a reason to do this, that is unrelated to the actual content of the patent applications, and there is some general principle or intention at play. But I will update the question to include the links. – Keir Finlow-Bates – 2018-08-17T15:27:53.493

This might come down to guessing. – DonQuiKong – 2018-08-17T22:40:08.637

They did it to get one narrow patent issued early while continuing to fight for a broader patent. The continuation application (15/851,879) was filed with the narrowest claim and filed with an optional costly process that provides accelerated examination. IBM got a notice of allowance on the continuation but the parent (15/429,121) application is still pending. To follow the details on a pending patent application use the USPTO's Public PAIR.
