Innovation, Patents and R&D[color=rgb(0, 137, 201) !important]Innovation and Development Around the World (1960-2000) by Daniel Lederman and Laura Saenz at the World Bank offers data on 'innovativ activities' from the 1960s onwards.
$$ The OECD maintains [color=rgb(0, 137, 201) !important]OECD.stat which has statistics on R&D, patents and other science & technology topics. Provision is limited to the OECD member states, the BRICS and a small number of other countries.
UNESCO provides statistics on [color=rgb(0, 137, 201) !important]R&D expenditure and personnel in their Data Centre, although it seems this data does not stretch further back than 1996.
The World Intellectual Property Organisation (WIPO) publishes the [color=rgb(0, 137, 201) !important]World Intellectual Property Indicators which includes for instance data for "Patent applications by patent office (1883-2008)" (read: country) which can be downloaded as excel or CSV file. Similarly of great interest should be "Patent grants by patent office (1883-2008)" and other statistics on 'Patents in Force' and 'Patent Intensity'. WIPO also has further resources on trademarks and plant varieties(!) among others. A second resource for patent data is the European Patent Office (EPO) which has a number of [color=rgb(0, 137, 201) !important]free databases on its website.

The World Intellectual Property Organisation (WIPO) also offers [color=rgb(0, 137, 201) !important]WIPO Lex, a "one-stop search facility for national laws and treaties on intellectual property (IP) of WIPO, WTO and UN Members".
Diego Comin and Bart Hobijn constructed the [color=rgb(0, 137, 201) !important]Historical Cross-Country Technology Adoption (HCCTA) dataset, available at NBER. This data allows for the analysis of the adoption patterns of some of the major technologies introduced in the past 250 years across the World's leading industrialized economies. This comes as an excel file with macros included, but if you prefer to play around with full data you can download the ASCII version.
Fulvio Castellacci and Jose Miguel Natera have created a balanced panel dataset for cross-country analyses of national systems, growth and development ([color=rgb(0, 137, 201) !important]CANA) hosted by the Norwegian Institute of International Affairs. The originality of this dataset (which draws on a variety of sources) is in that the gaps in the data have been filled, using a methodology of multiple (and repeated) imputations by two political scientists, Honaker and King (2010). I have not looked at the [color=rgb(0, 137, 201) !important]Castellaci & Natera paper describing the data construction and robustness checks in detail, but am a priori quite sceptical about imputations: these macro variables are likely to be integrated, so imputations could be rather misleading. On the other hand, missing data is a serious problem for a lot of the dimensions they consider: (1) Innovation and technological capabilities; (2) Education and human capital; (3) Infrastructures; (4) Economic competitiveness; (5) Social capital; (6) Political and institutional factors. There are a total of 41 indicators for 134 countries over the period 1980-2008. The data is in excel format and well-documented. I'd say keep an eye out for reviews and applications of this dataset.
The [color=rgb(0, 137, 201) !important]Agricultural Science and Technology Indicators (ASTI) are provided by IPRI. These are agricultural R&D indicators for developing countries only, with varying time-series coverage (earliest time around 1970, most recent up to around 2002). The data is split by institutional category (Higher Education, Private, Public Sector, NFP, government agencies) and provides numbers on researchers and R&D expenditure on agriculture.
For data covering agriculture R&D in developed countries check out the 'Science & Technology' section of the UNESCO[color=rgb(0, 137, 201) !important]database.
