The data is somewhat like below, but its a huge dataset containing more

1|1999|2000|H04Q007/32
1|1999|2000|G06K019/077
1|1999|2000|H01R012/18

HOW TO FILTER DATA
Try the code below:
df <- read_delim("C:/Users/lruan1/Desktop/1112.csv", "|", escape_double =
FALSE, trim_ws = TRUE)
df_new <- subset(df,df$IPC == 'H04M001/02'| df$IPC == 'C07K016/26' )
You can add more condition with "|" in the subset function. Good luck!
