How to read extract data between parantheses and print it to another file

I am looking a method to extract a particular text from multiple parentheses and wanted to store in a file. The content looks like this.

{& Vendor CGIO} 1100 650} {{& IP_OWNER cjohn} 1100 550} {{& Product pk_sgmii_serdes_sx_ico_idac_sw_by2} 1100 450} {{& DATE_TIME Aug 29 03:27:36 2016} 1100 750} {{& Version 1.1} 1100 350} {{& PDK_RELEASE_VERSION V1} 1100 850}

I wanted to extract following and print into a file.

& Vendor CGIO
& IP_OWNER cjohn
& Product pk_sgmii_serdes_sx_ico_idac_sw_by2
& Version 1.1

I tried using cut command but its not so useful to extract all variables.

cat Tags_file | cut -d '{' -f2 | cut -d '}' -f1

First, change all {& to newlines, then get rid of the remaining noise (note that I removed the initial & also):

$ echo "{& Vendor CGIO} 1100 650} {{& IP_OWNER cjohn} 1100 550} {{& Product pk_sgmii_serdes_sx_ico_idac_sw_by2} 1100 450} {{& DATE_TIME Aug 29 03:27:36 2016} 1100 750} {{& Version 1.1} 1100 350} {{& PDK_RELEASE_VERSION V1} 1100 850}" 
| sed 's/{&/\n/g' | awk -F\} '{ print $1 }'

 Vendor CGIO
 IP_OWNER cjohn
 Product pk_sgmii_serdes_sx_ico_idac_sw_by2
 DATE_TIME Aug 29 03:27:36 2016
 Version 1.1
 PDK_RELEASE_VERSION V1

Try 

grep -Poh '(?<={)& (?!DATE|PDK)[^}]+' Tags_file

What I got:

& Vendor CGIO
& IP_OWNER cjohn
& Product pk_sgmii_serdes_sx_ico_idac_sw_by2
& Version 1.1

Just what you needed. (excluded DATE_TIME and PDK as in your example)

Perhaps while loop will also print the outputs:

my $str = '{& Vendor CGIO} 1100 650} {{& IP_OWNER cjohn} 1100 550} {{& Product pk_sgmii_serdes_sx_ico_idac_sw_by2} 1100 450} {{& DATE_TIME Aug 29 03:27:36 2016} 1100 750} {{& Version 1.1} 1100 350} {{& PDK_RELEASE_VERSION V1} 1100 850}';

print "$1\n" while($str=~m/\{([^\{\}]*)\}/g);

Using grep -oP with lookaround based regex:

grep -oP '(?<={)[^{}]+(?=})' file

& Vendor CGIO
& IP_OWNER cjohn
& Product pk_sgmii_serdes_sx_ico_idac_sw_by2
& DATE_TIME Aug 29 03:27:36 2016
& Version 1.1
& PDK_RELEASE_VERSION V1
