This will make it more complicate to know where to start/stop. Please post a complete example of the real file.

@R. Singh
Code:
awk '
	{
	v=$0			# stor line $0 in variable v
	gsub(/.*\(|\).*/,x,v)	# remove all text before "(" and after ")" in variable v
	s=s?s OFS v:v		# if s does not exist s=v, if s exist append v to s using OFS a separator s=s OFS v (This prevent a blank space in front of line)
	}
	/\./ {			# if line does contain a "." we are on last line.
		print s		# print the created s
		s=""		# clear s
		}
	' file

Changing RudiCs code we can do this regarding () is changed to ""
Code:
cat file
2007_08_07_IA-0100-014_"January".PDF
2007_08_07_IA-0100-031_"January February March
April June July".PDF
2008-02-28_KR-1022-003_"January
febuary
march april
may".CSV


Code:
awk -F\" '{while ($0!~/\./) {getline x;$0=$0" "x}} {print $2}'

January February March April June July
January febuary march april may

Each command/solution we give is coded for a different pattern. If you come with new patterns every time and say that it is not working, I don't think we can do much!
Try to understand the solutions which are given and extend/modify for your needs.

just check both the file are same, just content was different.
but still code is not working.
It's not a different pattern.
